Abstract
A threaded inline swivel has a first nut and an opposite second nut each having the form of a generally hollow cylinder with an open end to receive fuel. Each nut has a collar that has a common nominal diameter. A collar provides at least two faces for gripping by a wrench. Each nut has threading for connection to a hose or other fitting. To further seal the swivel to a hose or a fitting, at least one O-ring and at least one gasket are provided as alternative embodiments. In a further alternate embodiment, the swivel has a threaded second nut and an opposite barbed end on the first nut with a clip. The first nut has its chamber that constricts in diameter through a throat as it enters the second nut. The swivel in all embodiments provides for flow of fluid through it with little turbulence.
Description
- This threaded inline swivel relates in general to means for connecting coaxial hoses, fittings, and nozzles used by motorists for fuel dispensing at a service station, and more specifically to improvements within the swivel allowing for concentric rotation of hoses, nozzles, and fittings connected thereto without leakage of fuel therefrom. A unique aspect of the present swivel is a male nut that constricts its inner diameter so that it fits within a female nut with reduced disruption to fuel flow. This invention is especially useful when applied in a fuel line at its connection to a nozzle where the nozzle may turn axially relative to the to hose.
- Upon arriving at a pump of a service station, a motorist views a nozzle connected to a length of hose, and the hose connected to the pump. The lengths of hose, fittings, and nozzles require connection among themselves and to service station pumping facilities. Hoses extend from fixed and rigid piping extending from the pump, generally concealed from a motorist. The hoses may extend from the side of the pump, approximately midway on its height or from overhead of the pump, descending to the typical usage height of a motorist. Hoses, manufactured to specific lengths, generally extend continuously from the pump to the nozzle. However, hoses, fittings, and nozzles interconnect in a generally linear path for conveying fuel from the pump to the motorist's fuel tank. At a service station, the nozzle enters the motorist's fuel tank at one angle while the hose extends from the pump at a different angle. Though hoses and select fittings can twist to a degree and accommodate the difference in angles, in time hoses where from such twisting. Where a hose connects to a rigid fitting, the fitting may not tolerate such a change in angles through the hose to it.
- Further, numerous swivels in the prior art furnish rotation between connected hoses and fittings, and more particularly, such swivels normally see use in lines containing fuel. Generally swivels have use in those situations where the fuel line leads from a fuel dispenser to a nozzle.
- Swivels also encounter forces imposed upon them by the service station environment, often errant motorists. Swivels may endure unbalanced internal forces as in a nuisance break or drive off. In such a nuisance break, greater fluid forces are exerted in one direction upon one part of the swivel than upon the other. When spontaneous and unbalanced high pressures are encountered, the pressure exerted upon one component of the swivel in one direction, substantially differs from the fluid pressure that may be exerted upon the other components of the swivel, and therefore, this pressure disparity tends to increase the risk of premature separation or failure of a swivel, in an untimely and dangerous fashion. This can and has occurred particularly where the fluid pressure in the hose may undergo a phenomenon that is equivalent to “water hammer.”
- The lengths of hose, fittings, and nozzles require connection among themselves and to service station pumping facilities. Hoses, fittings, and nozzles have swivels, often near the pump, that rotate when an errant motorist drives away with a hose in a vehicle, and thus prevent a spill or worse a fiery catastrophe. Until such an event, a swivel joins two sections of a fueling line or fittings and permits passage of fuel therethrough. As fuel pumps through the flow line, pressure spikes significantly and substantially throughout the hose, momentarily, and even at the location of a swivel, as when the flow is suddenly stopped, as for example, by the automatic shutoff by a nozzle when the fuel tank is full. Hence, leakage at such couplers has frequently occurred in the field, and on occasion, as previously explained, untimely separation or damage of the swivel has happened.
- Also, where a hose connects to a nozzle or to a fitting, a swivel joins the two adjacent components for continuous flow there through while allowing for coaxial rotation.
- Another swivel connector appears in U.S. Pat. No. 4,615,547 to Sutcliffe and Fink. This connector has a pair of swivel connectors joined upon a common boss. One swivel rotates upon an axis general perpendicular to the flow direction. Each connector has a male end with a threaded swivel nut thereon and an opposite female end with a thread fitting engaged therein. Each swivel alters the flow path through an approximate ninety degree bend and offsets the flow approximately one half of the diameter of the female end. The male end also rotates at an angle to the female end much like a bending elbow, so that hoses connected thereto also bend. In bending similar to a hinge, the swivels cause hoses, fittings, and nozzles to attain a non-linear flow path that may affect fuel flow. The hinge like bending also causes the connected parts to occupy slightly more space in the compact service station environment.
- The present invention overcomes the limitations of the prior art. Where, the present invention, a threaded inline swivel, uses coaxial male and female nuts that mutually rotate upon an axis parallel to the length of the swivel and the direction of flow.
- A threaded inline swivel begins with a male nut and an opposite female nut each having the form of a generally hollow cylinder with an open end to receive and to dispense fuel. The male nut and the female nut each have a collar that has a common diameter. Each collar provides at least two faces for gripping of the adaptor by a wrench or other tool. The male nut and the female nut each have threading for connection to a hose or other fitting. Within the interior of the swivel, the two ends of the male nut and the female nut open into a smooth walled chamber that allows for uninterrupted fluid flow. To further seal the connection of the swivel to a hose or a fitting, at least one O-ring and at least one gasket are provided as alternative embodiments. In a further alternate embodiment, the swivel has a threaded female nut and an opposite barbed end on the male nut with a clamp. The male nut has its chamber that constricts in diameter through a throat as it enters the female nut. The swivel in all embodiments provides for flow of fluid through it with few if any turbulent effects.
- Generally, the threaded ends of the nuts simply turn into cooperating female threaded hoses and fittings. A user places a tool upon the collar thus gripping the male nut, the female nut, or both for installation of a second hose or fitting at low labor and equipment cost. Cooperating races upon the male nut and the female nut and various size bearings keep the nuts connected but allow for coaxial rotation parallel to the length of the swivel and fluid flow. Strategically located O-rings provide for fluidic sealing of the swivel to various hoses and fittings in the flow line from a fuel pump. The present invention does not require the use of any strong biasing springs, or other mechanisms, to provide for its quick and simple installation.
- Therefore, it is an object of the invention to provide a new and improved threaded inline swivel for fuel nozzles, fittings, hoses, and lines.
- It is a further object of the present invention to connect two fluid transmitting items generally coaxially for minimal turbulent flow.
- It is a further object of the present invention to provide a threaded inline swivel that allows for grasping by a tool upon its center.
- It is a further object of the present invention to dissipate any abrupt pressure spikes generated within the threaded inline swivel during its functioning within a flow line thus preventing undesirable fuel leakage or untimely separation of hoses and fittings.
- Another object of this invention is to provide a threaded inline swivel where it's sealing O-rings and gaskets are normally located within seats and cooperating with threads respectively during normal and routine usage of the adaptor when installed within a fluid flow line.
- Another object is to provide such a threaded inline swivel capable of connecting to a variety of hoses and fittings having female ends, threaded and unthreaded.
- Another object is to provide such a threaded inline swivel that has a low cost of manufacturing so the purchasing people and organizations can readily buy the adaptor through stores and supply sources.
- These and other objects may become more apparent to those skilled in the art upon review of the invention as described herein, and upon undertaking a study of the description of its preferred embodiment, when viewed in conjunction with the drawings.

- The present art overcomes the prior art limitations of various swivels by providing a swivel that allows for coaxial rotation of two halves and includes a tapered throat to minimize adverse fluid flow effects. The
present invention 1 appears inFIG. 1 , and has a generally hollow cylindrical form with afirst end 2 and an oppositesecond end 3. As shown both ends 2, 3, haveexternal threads 4, here shown as right hand, coarse. The threads continued for approximately four revolutions around the circumference of the ends. The threads extend inwardly upon afirst nut 5 and an oppositesecond nut 6. The first nut and the second nut are hollow and have sufficient length for a solid connection of the swivel to a hose or other fitting. The first nut also has atip 15 here shown slightly extending from the threads of the second end towards the right of the figure. The tip will be further shown inFIGS. 3 , 5. Inwardly, each nut has a notch upon its perimeter, afirst notch 7 at the end of thethreads 4 on thefirst nut 5, and asecond notch 8 opposite the first notch where thethreads 4 end on thesecond nut 6. Thenotches threads 4 and theends first collar 9 of a diameter noticeably greater than diameter of the threads. The collar has a thickness, along the length of the swivel, suitable for gripping by a tool, such as a wrench or channel lock pliers. The collar extends around the circumference of the swivel, that is, perpendicular to the length of the swivel. The collar is generally round but for at least twofaces 9 a. The second nut has asecond collar 16 also of a diameter noticeably greater than diameter of the threads and generally the same diameter as the first collar for overall smoothness of the swivel. This collar also has a thickness, and faces 9 a suitable for gripping by a tool, such as a wrench or channel lock pliers. The second collar also includes acap 17 generally centered in oneface 9 a. The cap covers the aperture in the second collar for admission of bearings as later shown inFIG. 2 . As an alternate embodiment, the adaptor includes at least one O-ring 10 and at least onegasket 11. The O-ring has a generally O shape as later shown inFIG. 6 and a rounded cross section. The gasket also has a generally rounded shape as shown later inFIG. 6 but with a squared cross section. - Turning the swivel axially one quarter turn downward from
FIG. 1 ,FIG. 2 shows theswivel 1 with thefaces 9 a downwardly and the cap at the lowest to portion of the swivel. This figure shows a partial section through thecollars second collar 15 along line A-A. Inwardly from the cap, the second collar has anaperture 20 into which fits thecap 17 and afirst bearing 18. The first bearing remains sandwiched between the collar and a portion of the first nut as later shown inFIG. 3 . To the left of the bearing in the figure, the first nut is includes afirst O ring 19. Thefirst O ring 19 occupies the corner formed from the inner edge of the second nut and the inside corner of the first nut, also as later shown inFIG. 3 . With the cap in place, the first bearing remains in place. With the cap removed, the first bearings can exit the second nut or alternatively be installed into the second nut. -
FIG. 3 provides a longitudinal section view through the swivel with the first nut connected to the second nut: As above, thefirst nut 5 has anopen end 2 that hasexternal threads 4. Inward of the threads, the first nut has thefirst notch 7 and then thecollar 9. Forward of the collar, the first nut has itsneck 22 that fits within the length of the second nut. The neck generally has a slightly lesser diameter than the inner diameter of the second nut. The neck also has a noticeably lesser diameter than theend 2. Opposite thecollar 9, the neck has thetip 15, here shown with a slight bevel to ease assembly. The neck is also a generally hollow cylinder forming achamber 23 through which fuel flows. The chamber has a narrow diameter within the neck and then a wider diameter proximate theend 2. The chamber has athroat 24 having the widest diameter of the chamber and locating inwardly from theend 2 to approximately where the collar adjoins the first notch. The widest diameter is shown asline 24 a. Inward of the widest diameter, the throat curves in a slightly concave manner for a short distance to the second widest diameter,line 24 b. From that line, the throat has its diameter decrease in a linear manner going forward to the neck to line 24 c, the third widest diameter. Inward of the third diameter, the throat curves in a slightly convex manner for a short distance to attain the inner diameter of the neck as atline 24 d. The transition in chamber diameter from thethroat 24 to theneck 22 occurs over a portion of the first nut call theconstriction 25. The constriction to reduces the diameter of the throat by approximately 40% as it transitions to the diameter of the neck. The constriction, being hollow and round like the throat and the neck allows for the passage of fuel through it at the least amount of adverse fluid flow effects. Outwardly from the constriction towards the neck, the neck includes arace 21 of a suitable width to admit thefirst bearings 18. - And as above, the
second nut 6 has itssecond end 3 here shown to the right, proximate the emplacedtip 15. The second end is generally hollow for admission of the neck therein. The second end has itsexternal threads 4, thesecond notch 8, and thesecond collar 16. Within the second nut, the second end has asecond race 26, athird race 27, and afourth race 28 mutually spaced apart and concentric. The second race and the third race extend outwardly into the end to admit the second O-ring 29 and the third O-ring 30. The second and third O-rings have an inner diameter slightly smaller than the outer diameter of the neck for a snug fit, preventing fuel leakage. Away from the end and generally inside of the threads, the second nut has thefourth race 28 that extends outwardly into the nut more than the second and third races. The fourth race admits thesecond bearings 31 that contact the surface of the neck, allowing rotation of the neck of the first nut relative to the second nut. Then within thecollar 16, the second nut also has thefifth race 32 that admits thefirst bearings 18, once more for rotation of the two components of the invention. Generally, thefirst bearing 18 has a larger diameter than thesecond bearing 31. And outwardly from the fifth race, the second collar and the first collar, outwardly from theline 24 c, have thefirst O ring 19 locating between the two collars. - This embodiment of the inline swivel has a generally round shape when viewed on end in
FIG. 4 . Theinline swivel 1 has itssecond nut 6 with thesecond collar 16 that generally defines the maximum diameter, that is, width of the swivel as seen by the motorists after its installation. The collar, generally round, has two spaced apart and mutuallyparallel faces 9 a. The faces allow for a tool, such as a wrench or channel lock pliers, to grip thesecond nut 6 of the inline swivel. The tool then either turns the second nut into a hose or fitting, or holds the second nut to steady as a hose or fitting turns upon either stem. Stepped inwardly from the collar's diameter, the second nut has its threads, as at 4, here shown in an end view of the end itself 3. In the center foreground of the figure within the end, theneck 22 extends outwardly from the end, that is, out of the plane of the figure. The tip is generally beveled, as previously shown inFIG. 3 . Within the tip, the is neck has thechamber 23 through which fuel flows from the first nut through the second nut. -
FIG. 5 then shows theinline swivel 1 in an exploded view of thefirst nut 5 and thesecond nut 6. Thefirst nut 5 begins with itsthroat 24 leading into the nut from theend 2. The end hasthreads 4 for connection to a hose, fitting, or nozzle. The threads continue inwardly to thefirst notch 7. The threads generally maintain a constant outer diameter for the end while the throat has its constant inner diameter through the threaded portion of the end up to line 24 a within the first notch as previously shown. Inwardly from the first notch, thefirst nut 5 expands in width at thefirst collar 9. Thecollar 9 is generally round except for the two flat, mutuallyparallel faces 9 a suitable for a tool. The collar has a greater diameter than thethreads 4 and generally establishes the maximum width of the swivel. Opposite the threads, theneck 22 extends from the collar further inwardly of the invention. The neck is generally a hollow cylinder of lesser diameter than the threadedend 2. Proximate the collar, the neck has therace 21 that receives thebearings 18. The race has a slight recess into the diameter of the neck, previously shown inFIG. 3 , and fits between first step 21 a andsecond step 21 b. The first step and the second step are mutually spaced apart bands having a thickness and a diameter greater than that of the neck. The first step and the second step extend around the circumference of the neck and each has a generally square like cross section. The spacing between the first step and the second steps is generally that of the diameter of thefirst bearings 18. Both the first step and the second step have a position proximate thecollar 9 and removed from thetip 15. Inwardly from therace 21, the neck extends to its maximum length shown at thetip 15. The tip has a beveled surface at the terminus of thefirst nut 5 opposite theend 2. Outwardly from the first nut, the swivel has the first O-ring 19 with an inner diameter that fits snugly upon the first step 21 a contiguous with the collar. The first O-ring has a generally round shape and a round cross section. Then outwardly from the first O-ring, the swivel includes a set offirst bearings 18, approximately 0.125 inch to approximately 0.3 inch in diameter, preferably 0.1875 inch in diameter. Though this figure shows ten first bearings, the preferred embodiment includes fifteen first bearings generally positioned within therace 21, as previously shown inFIG. 3 . - Outwardly from the
first bearings 18, the swivel has thesecond nut 6 with itssecond collar 16. The second collar has a generally round shape except for twoflat faces 9 a. Centered within the second collar, around aperture 32 has a diameter similar to that of the first step 21 a. The aperture's diameter admits theneck 22 into the second nut. Inwardly from the aperture, the second collar has athird step 33 that increases the thickness of the second nut proximate the threads. The third step has an inner diameter similar to the outer diameter of theneck 22 and less than the diameter of thesecond step 21 b. Inwardly from the second step, the second nut continues in a hollow cylindrical manner towardsend 3. Proximate thesecond end 3 and interiorly, the second nut has thefourth race 28, generally of greater diameter than the third step that receives thesecond bearings 31, and thesecond race 26 and thethird race 27 that receive O-rings FIG. 3 . And outwardly from theend 3, the swivel includessecond bearings 31, second O-ring 30, and third O-ring 29 shown concentrically. Though the figure shows fourteen bearings, the preferred embodiment includes twenty two second bearings. The second bearings have a diameter of approximately 0.0625 inch to approximately 0.25 inch. The second and third O-rings have an inner diameter similar to the outer diameter of the neck, a round shape, and a generally round cross section. - Generally for closing off the threaded connection of a hose or fitting to the
swivel 1 proximate thenotches gasket 5 and an additional O-ring 10 as shown inFIG. 6 . The O-ring 10 is generally round within aninner edge 10 a at an inner diameter and anouter edge 10 b at an outer diameter greater than the inner diameter. The O-ring has a generally round cross section, radially, between the inner edge and the outer edge. The inner diameter is generally slightly more than the diameter of the adaptor at the notches but less than the diameter of thethread 4. The O-ring has a material that allows for slight stretching for placement over the threads and compression by a hose or other fitting when connected thereto. Alternatively, the swivel has thegasket 11, generally round, with aninner rim 11 a at an inner diameter and arim 11 b at the outer diameter of the gasket. The inner diameter of the gasket generally exceeds that of the O-ring 10. The inner rim and rim of the gasket form a generally square cross section as later shown inFIG. 7 . Upon the inner rim, the gasket has a plurality of spaced flutes 13. Here the flutes have a generally semi-circular shape extending inwardly into the gasket, towards its nominal center. The radius of each flute begins at the inner rim and turns through 180 degrees of arc. Preferably, the gasket has an even number of flutes, here shown as six. The flutes engage thethreads 4 of eachstem threads 4. -
FIG. 7 then shows a cross sectional view of thegasket 11. The gasket has therim 11 b that faces outwardly from the gasket and swivel when installed, and the oppositeinner rim 11 a upon the interior of the gasket. Perpendicular to the rim and the inner rim, anedge 5 c joins the two rims upon both sides of the gasket. The edges and the two rims generally form a square cross section as shown in the top and the bottom of the figure. Upon the inner rim, the gasket has theflutes 13, generally equally spaced. Each flute has athin tip 13 a away from the inner rim than merges withshoulders 13 b of greater thickness than the tip. The shoulders join to the inner rim. The flutes and the tips extend inwardly, that is, away from the inner rim. -
FIG. 8 then shows the perimeter of the gasket more closely. Though showing a portion of the perimeter in this figure, the structure extends upon the entire perimeter of the gasket. The gasket has theinner rim 11 a with aflute 13, rim 11 b, andedge 5 c as before. The rim though in this embodiment has aslight slope 5 d, extending from left to right in the figure. The slope is approximately 1 to 4 degrees and oriented so that the bottom of the slope advances towards the collar upon turning the gasket on a stem. Theedge 5 c further includes ataper 5 e partially along the length of the edge. The taper begins at the thickness of the gasket and then narrows slightly about midway along the edge. - Another form of the
edge 5 c appears inFIG. 8 a with a perimeter sectional view. The gasket begins with aflute 13 upon theinner rim 11 a with the opposite, or outwardly, rim 11 b as before. The rim has itsslope 5 d outwardly from the inner rim similar to that shown inFIG. 8 . Unlike thesmooth edges 5 c, this embodiment has three mutually spaced apartbarbs 14 here shown in section. The barbs appear as concentric rings upon the edges when seen as inFIG. 6 . The barbs, as a group, extend at least midway from the inner rim to the rim. The barbs have their narrowest portion outwardly towards the rim and their thicker portion inwardly towards the inner rim. Outwardly from thebarbs 14, the gasket has atip 5 f generally proximate the rim. The tip generally lacks barbs or other securing surface features.FIG. 8 b orients the sectional view to a flat orientation as a hose or fitting would abut the gasket. InFIG. 8 b though, therim 11 b at thetip 5 f is generally square, or without a slope. This figure also shows a partial section of a flute where the tip extends inwardly from the shoulders. - A third form of the
edge 5 c appears inFIG. 8 c, also in a perimeter sectional view. The gasket has its flute extending inward from theinner rim 11 a with the opposite, or outwardly, rim 11 b as before. The rim has itsslope 5 d outwardly from the inner rim similar to that shown inFIG. 8 . This embodiment also has three mutually spaced apartbarbs 14 here shown in section. The barbs appear as concentric rings upon the edges when see as inFIG. 6 . These barbs, as a group, span from the inner rim to the rim. The barbs have their narrowest portion outwardly towards the rim and their thicker portion inwardly towards the inner rim. In this embodiment, the gasket lacks a tip as in the previous embodiments of the edges.FIG. 8 d orients the sectional view to a flat orientation as a hose or fitting would abut the gasket. Similar toFIG. 8 b, therim 11 b is generally square, or without a slope. The rim also truncates the outer barb on the top and bottom edges. This figure also shows a partial section of a flute where the tip extends inwardly from the shoulders. - A second embodiment of the swivel appears in
FIG. 9 in a side view. Thisswivel 1 also has a generally hollow cylindrical form with afirst end 2 and an oppositesecond end 3.

The threads extend inwardly upon thefirst nut 5 and an oppositesecond nut 6. The first nut and the second nut are hollow and have sufficient length for a solid connection of the swivel to a hose or other fitting. The threads upon the first nut, as at 4, have generally coarse form while the threads upon the second nut, as at 4 a, have generally fine form. Outwardly from thethreads 4 a of thesecond nut 6, thetip 15 of theneck 22 of thefirst nut 5 extends. - Inwardly, each nut has a notch, a
first notch 7 at the interior ending of thethreads 4 on thefirst nut 5. Thesecond nut 6 also has aflange 35 inwardly of the interior ending of thethreads 4 a and asecond notch 8 inwardly of the flange opposite the first notch where thethreads 4 a end on thesecond nut 6. Thenotches threads ends second notch 8 receives a fourth O-ring 34 upon its circumference. This O-ring has a generally round shape with a round cross section. This O-ring has an outer diameter similar to the outer diameter of the flange. Centered between the two stems, this embodiment of the swivel also has acollar 9 on thefirst nut 5 and asecond collar 16 on thesecond nut 6. Each collar has a diameter noticeably greater than diameter of the threads. Each collar has a thickness, along the length of the swivel, suitable for gripping by a wrench or other tool. Each collar extends around the circumference of the swivel, perpendicular to the length of the swivel. The collar is generally round except for twofaces 9 a later shown inFIG. 9 . Thesecond collar 16 also includes thecap 17 upon theaperture 20 for insertion of thefirst bearings 18 into the invention. As an alternate embodiment, the swivel includes at least onegasket 11 that has a generally rounded shape as previously shown inFIGS. 4 , 5 with the variations shown inFIGS. 6-8 d. - Turning the swivel axially one quarter turn downward from
FIG. 9 ,FIG. 10 shows this alternate embodiment of theswivel 1 with thefaces 9 a downwardly and the cap at the lowest portion of the swivel. This figure shows a partial section through thecollars second collar 16 along line A-A. Inwardly from the cap, the second collar has theaperture 20 into which fit thecap 17 and thefirst bearings 18. The first bearing remains sandwiched between the collar and a portion of the first nut as later shown inFIG. 11 . To the left of the bearing in the figure, the first nut includes afirst O ring 19. Thefirst O ring 19 occupies the corner formed from the inner edge of the second nut and the inside corner of the first nut, also as later shown inFIG. 11 . With the cap in place, the first bearings remain in place. With the cap removed, the first bearings can exit the second nut or alternatively be installed into the second nut. - Within its interior, the swivel provides for flow of fluid, mostly fuel, as shown in
FIG. 11 , a longitudinal section view through the swivel with the first nut connected to the second nut. As above, thefirst nut 5 has anopen end 2 that hasexternal threads 4. The first end includes a slightinward bevel 10 that extends around the circumference of the first end. Inward of the threads, the first nut has thefirst notch 7 and then thefirst collar 9. Forward of the collar, the first nut has itsneck 22 that fits within the length of the second nut. The neck generally has a slightly lesser diameter than the inner diameter of the second nut. The neck also has a noticeably lesser diameter than theend 2. Opposite thecollar 9, the neck has thetip 15, here shown to the far right with a slight bevel to ease assembly. The neck is also a generally hollow cylinder forming achamber 23 through which fuel flows. The chamber has a narrow diameter within the neck and then a wider diameter proximate theend 2. The chamber has athroat 24 having the widest diameter of the chamber and locating inwardly from theend 2 to approximately where the collar adjoins the first notch. The widest diameter is shown asline 24 a. Inward of the widest diameter, the throat curves in a slightly concave manner for a short distance to the second widest diameter,line 24 b. From that line, the throat has its diameter decrease in a linear manner going forward to the neck to line 24 c, the third widest diameter. Inward of the third diameter, the throat curves in a slightly convex manner for a short distance to attain the inner diameter of the neck as atline 24 d. The transition in chamber diameter from thethroat 24 to theneck 22 occurs over a portion of the first nut call theconstriction 25. The constriction reduces the diameter of the throat by approximately 40% as it transitions to the diameter of the neck. The constriction, being hollow and round like the throat and the neck allows for the passage of fuel through it at the least amount of adverse fluid flow effects. Outwardly from the constriction towards the neck, the neck includes arace 21 of a suitable width to admit thefirst bearings 18. - And as above, the
second nut 6 has itssecond end 3 here shown to the right, proximate the emplacedtip 15. The second nut continues the hollow shape of the first end through to its opening at thesecond end 3. The second end also has an inward bevel as at 10. The second end is generally hollow for admission of the neck therein. The second end has itsexternal threads 4 a, thesecond notch 8, and thesecond collar 16. The second threads have finer pitch than the threads upon the first nut. Inwardly from the second threads opposite the second end, the second nut has theflange 35 upon its circumference. The flange has a generally square cross section as shown and a diameter greater than that of the threads but less than that of thesecond collar 16. Between the flange and the s second collar, the second nut has thesecond notch 8 that receives the fourth O-ring 34. The fourth O-ring has an outer diameter slightly more than the diameter of theflange 35. - Within the second nut, the second end has the
second race 26, thethird race 27, and thefourth race 28 mutually spaced apart and concentric. The to second race and the third race extend outwardly into the end to admit the second O-ring 29 and the third O-ring 30. The second and third O-rings have an inner diameter slightly smaller than the outer diameter of the neck for a snug fit, preventing fuel leakage. Away from the end and generally inside of the threads, the second nut has thefourth race 28 that extends outwardly into the nut more is than the second and third races. The fourth race admits thesecond bearings 31 that contact the surface of the neck, allowing rotation of the neck of the first nut relative to the second nut. Then within thecollar 16, the second nut also has therace 21 that admits thefirst bearings 18, once more for rotation of the two components of the invention. Generally, thefirst bearing 18 has a larger diameter than thesecond bearing 31. The second collar and the first collar, outwardly from therace 21 and theline 24 c respectively, have thefirst O ring 19 locating between the two collars. - The second end opens into the
second nut 6 that has the O-ring 19 upon thesecond notch 8. As shown in this view, thesecond notch 8 has a larger diameter than thefirst notch 7, that is, the second notch is shallower than the first notch. The diameter of the second notch and the outer diameter of the O-ring cooperate so that the fourth O-ring remains within the diameter of the flange. In this view, thefirst end 2 admits fuel into the first stem that flows smoothly through thesecond nut 6 and out of thesecond end 3 where the smoothly flowing fuel passes through achamber 23, generally a hollow cylinder, that extends through both stems 5, 6 and through thecollar 16. - This alternate embodiment of the inline swivel has a generally round shape when viewed on end in
FIG. 12 . Theinline swivel 1 has itssecond nut 6 with thesecond collar 16 that generally defines the maximum diameter, that is, width of the swivel as seen by the motorists after its installation. The collar, generally round, has two spaced apart and mutuallyparallel faces 9 a. The faces allow for a tool, such as a wrench or channel lock pliers, to grip thesecond nut 6 of the inline swivel. The tool then either turns the second nut into a hose or fitting, or holds the second nut steady as a hose or fitting turns upon either stem. Stepped inwardly from the collar's diameter, thesecond nut 6 has the fourth O-ring 34 extending slightly outwardly from theflange 35. Inside of the flange, the second nut has its threads, as at 4 a, here shown in an end view of the end itself 3. In the center foreground of the figure within the end, theneck 22 extends outwardly from the end, that is, out of the plane of the figure.
