For the purpose of oversimplifying, in the following description with reference to single valve 10.

Valve 10 comprises substantially: plate 11, its carrying of radial arm by carousel; Filling head 12, the axis A that it can be parallel along the axis with respect to carousel slides with respect to this plate, thereby shifts to or move apart container 4; And flange 20, but it is connected and is intended to aim at the center of the neck 6 of container 4 with filling head 12 with delivery mode.

Filling head 12 comprises substantially:

-element 15, it is arranged in cavity 16 in the mode of slipper seal along axis A, and cavity 16 is limited by the plate fixing with respect to axis A 17;

-main body 18, it is connected with plate 11 elasticity, limit the passage 19 fluidly be connected with basin 2a, but and have and the first axial end portion (not shown) of element 15 connections and second axial end portion that with delivery mode with flange 20 be connected relative with the first axial end portion; And

-shutter elements 21, it can slide and be connected with cross member 22 elasticity of main body 18 with respect to main body 18.

Or rather, cavity 16 is connected with the first feedway for pressure fluid via the passage 17' that runs through plate 17, and element 15 closed cavity 16 on the sidepiece of flange 20.

Thus, when pressure in cavity 16 increases, filling head 12 and flange 20 are shifted to container 4 along the direction translation of the A that parallels to the axis, until they arrive dipping shown in Fig. 2 and Fig. 3.

Similarly, during pressure decreased in cavity 16, filling head 12 and flange 20 parallel to the axis the A translation and move apart container 4, until they arrive the raised position shown in Fig. 1.

Main body 18 comprises substantially and integratedly:

-cross member 22;

The main portion 23 of-axis A, defined by cross member 22 and flange 20 respectively on the opposition side of its side at element 15 and element 15; And

-C shape end 25, it is arranged on the opposition side of cross member 22 and is connected with element 15 with respect to main portion 23.

The certainly main part 23 of passage 19 is with respect to laterally projection of axis A.

Cross member 22 and main portion 23 limits cavitys 24, and cavity 24 is sliding engaged to by shutter elements 21, but and fluidly is connected with basin 2b via passage 19 and is intended to be filled with fluid food.

Cavity 24 opens wide on the opposition side of cross member 22, and comprises substantially towards flange 20 from cross member 22:

-main cylindrical section 26;

-frusto-conical section 27, its convergent of opposition side at section 26; And

-pair of

cylinders shape section

29a, 29b (Fig. 1 to Fig. 6).

Particularly, section 29a has the diameter shorter than section 29b and connects with section 29b via the inclined-plane shown in Fig. 5 to 8.

End 25 specifically comprises the A with isolated the first wall of axis A, perpendicular to axis A the second wall passed by axis A and be parallel to the first wall and be shorter than the 3rd wall of the first wall of paralleling to the axis.

Main portion 23 also limits shoulder 13, and shoulder 13 is connected with plate 11 via the coil spring 14 with axis A.

Flange 20 extends symmetrically about axis A.

Flange 20 also comprises top surface 31a, the side surface with respect to axis A in radially outer 32 and the inner radial side surface 33 be arranged in section 29b substantially.

Inner lateral surfaces 33 specifically comprises: a plurality of radial projection 49 that replace, and it is suitable for the screw thread fit with the neck 6 of container 4; And a plurality of perforation grooves 50 that replace, its air that is suitable for allowing to be contained in the filling step in container 4 flows out flange 20 (Fig. 5 and Fig. 6).

Flange 20 also comprises shoulder 38, and shoulder 38, and engages with the axial end portion relative with cross member 22 of main portion 23 towards cross member 22 projections from top surface 31, and the through hole 35 that is communicated with cavity 24 fluids of restriction.

Flange 20 finally comprises the top surface 31b relative with top surface 31a.

Inner lateral surfaces 33 limits cavity 36, and cavity 36 is arranged on the opposite side in hole 35 with respect to main portion 23.Particularly, cavity 36 35 opens wide and on the opposite side in hole 35 towards hole, and has the radial dimension larger with respect to axis A than hole 35.

Shutter elements 21 comprises: bar 34, and it passes hole of cross member 22 and is connected to cross member 22 via coil spring 47 elasticity with axis A; And element 48, itself and bar 34 is integrated and the interior slip of cavity 37 that can limit in the end 25 by main body 18.

Bar 34 has the end 39a， end 39a relative with element 48 and has towards the frusto-conical configuration of flange 20 convergents and corresponding to the section 27 of cavity 24.Bar 34 also is suitable for having defined against main portion 23 hermetically the surface of section 27.

Bar 34 is hollow, and the bleed-off passage 39b be connected with basin 2b (only roughly illustrating) bar 34 coaxially.

Cavity 37 is connected with the second feedway for pressure fluid via the passage that runs through end 25, and element 48 is arranged on the sidepiece that cavity 16 faces container 4.

Like this, when pressure in cavity 37 increases, shutter elements 21 is shifted to container 4 until arrive off position (Fig. 2) along the direction translation of the A that parallels to the axis.In this off position, the end 39a of bar 34 abuts against the section 27 of cavity 24 hermetically.In this case, but fluid food can't flow to flange 20 from cavity 24.

Similarly, during pressure decreased in cavity 37, flashboard 21 parallels to the axis the A translation and moves apart container 4 until arrive open position (Fig. 3), and at this open position, but flashboard 21 allows fluid foods to flow to flange 20 from cavity 24.

But passage 19 and cavity 24 are defined for the first fluid path of fluid food.In the step of cartridge 4, when filling head 12 in dipping and shutter elements 21 when in an open position, this first fluid path fluidly is connected with the mouth 5 of container 4.

Otherwise when shutter elements 21 is in the closed position, but it stops fluid food to flow to the mouth 5 of container 4 from the first fluid path.

Passage 39b limits the second fluid path, in the step of cartridge 4, when filling head 12 in dipping and shutter elements 21 when in an open position, the air be contained in container 4 flows through this second fluid path.

Each valve 10 comprises distributing box 40, but fluid food can flow through this distributing box 40.

Advantageously, distributing box 40 is by flange 20 carrying conjugate foramens 35.

In the illustrated case, distributing box 40 is tubulose and is made by plastic material, and flange 20 is formed from steel.

Particularly, distributing box 40 is defined in the radially outer position with respect to axis A by the tubular wall 41 with axis A, and is defined in the inner radial position (Fig. 5 and Fig. 6) with respect to axis A by the cylindrical wall 42 that also has axis A.

Distributing box 40 also comprises the pair of cylinders shape wall 43 with axis A, the radial outside that this is arranged in the radially inner side of axis A and is arranged in axis A with respect to wall 42 with respect to wall 41 cylindrical wall 43.

Distributing box 40 also comprise with respect to axis A radially and from wall 42 to wall the 41 a plurality of walls 44 that extend.

Wall

41,42,43 limits a plurality of perforation sieve apertures 45 with intersecting of wall 44, but fluid food flows through sieve aperture 45 when shutter elements 21 is in an open position.

Preferably, but sieve aperture 45 have when flashboard 21 is in an open position and filling head 12 when dipping to allow the size of fluid food Uniform Flow.But but having by means of the surface tension of fluid food drop, sieve aperture 45 just after shutter elements 21 has arrived off position, also catches the size of fluid food drop.

Distributing box 40 axial length vertically is shorter than the axial length of flange 20.Flange 20 further is configured to: when flashboard 21 is in an open position and filling head 12 when dipping, cavity 36 neck by container 46 at least in part engages, and distributing box 40 on the direction of A that parallels to the axis, be positioned at container 4 mouth 5 above and with mouth 5 (Fig. 5 and Fig. 6) separated by a distance of container 4.

Like this, but distributing box 40 during the filling of container 4 never be contained in container 4 in fluid food contact.

Therefore, distributing box 40 allows to carry out " non-contact type " filling of container 4, but is particularly suitable for to the fluid food of container 4 filling room temperatures.

But distributing box 40 and flange 20 interconnect with delivery mode.

Or rather, wall 41 further comprises main cylindric part 46 and shoulder 51, and shoulder 51 has the radial dimension of the part of being slightly larger than 46 radial dimensions and is intended to coordinate with the stop edge (not shown) in hole 35 that distributing box 40 is locked in these holes itself.

Disclose the operation of valve 10 from state shown in Fig. 1, in Fig. 1, filling head 12 is in the closed position in raised position and shutter elements 21.

Subsequently, the first feedway of pressure fluid increases the pressure in cavity 16, determined filling head 12 along axis A towards container 4 translations.

During this translation, spring 14 shortens and shutter elements 21 remains in off position.

When translation finishes, filling head is in dip (Fig. 2), and in this dips, the center of the neck 6 of flange 20 aligning containers 4 and distributing box 40 are spaced apart with the mouth 5 of container 4 in the axial direction.

Now, the second feedway of pressure fluid reduces the pressure in cavity 37, has determined that shutter elements 21 raises along direction A with respect to filling head 12.

This rising has determined that the shortening of spring 47 and cavity 24 fluidly are connected with the sieve aperture 45 of distributing box 40, but allows fluid food to flow through mouth 5 and cartridge 4.

During the filling of container 4, air flows out and overflows via the groove 50 of flange 20 from the circular bizet of the mouth 5 that is positioned at distributing box 40 radial outsides with respect to axis A.

With reference to figure 4, Fig. 7 and Fig. 8, digital 10' means fillup valve according to another embodiment of the present invention.

Valve 10' is similar to valve 10, and hereinafter will be only with regard to it and the latter's difference, discloses; If of course, will be meaned by identical Reference numeral appropriate section or the equivalent of valve 10' and valve 10.

The difference of valve 10' and valve 10 is that distributing box 40' comprises substantially:

-with the cylindric passage 42' of axis A, its have the section 44' that engages with passage 39b and with axial relative the second section 45' of section 44', when filling head 12 in dipping and shutter elements 21 when in the closed position, in the neck 6 of the second section 45' in container 4 (Fig. 7 and Fig. 8);

-tubular wall 43', it engages with hole 35 and is spaced apart round section 46', and section 46' is folded between the section 44' and section 45' of passage 42' vertically; And

-a plurality of wall 47', its on the opposition side of axis A from section 45', 46' projection.

Each wall 47' comprises substantially:

-part 48', it is positioned on the plane of paralleling to the axis A and departing from respect to axis A, and is folded between section 46' and wall 43'; And

-part 49', it is from section 45' projection, and is positioned on the plane that tilts with respect to part 48' and is horizontal with respect to axis A.

But thus the wall 47' of every phase adjacency pair limit fluid food from cavity 24 to container the 4 passage 50' that flow through.Partly parallel to the axis A and partly extending transverse to axis A of each passage 50'.Passage 50' is also with respect to axis A interval equally on angle.

The axial length of section 45' is to make the first axial end portion that section 45' is relative with section 44' be positioned at a little the top of the top surface 31b that flange 20' is relative with top surface 31a.

Therefore, when filling head 12, when dipping, the first axial end portion of section 45' is positioned at neck 6 and below mouth 5.Once completed the filling of container 4, but the first axial end portion of section 45' just be contained in container 4 in fluid food contact.

In other words, distributing box 40' allows to carry out " contact " filling of container 4.Should " contact " but filling be particularly suitable for, to container 4 filling heat fluid foods, being in the temperature in scope between 80 to 95 degrees centigrade.

Wall 43' further comprises main cylindric part 49' and shoulder 51', and shoulder 51' has the radial dimension that is slightly larger than part 49' radial dimension and is intended to and coordinates that with hole 35 distributing box 40' is locked in hole 35.

The difference of flange 20' and flange 20 is that it comprises the packing ring 52'(Fig. 7 that is positioned at cavity 36 and is sealed and matched with wall 43').

By flange 20 and distributing box 40 are replaced with respectively to flange 20' and distributing box 40', can easily valve 10 be converted to valve 10'.

Only with regard to the difference of the operation of itself and valve 10, carry out the operation of open valve 10'.

Particularly, when filling head 12 when dipping, the screw thread couple of the side surface of flange 20' 33 and the neck 6 of container 4, and the first axial end portion of section 45' is positioned at neck 6 and the horizontal surface place below mouth 5.

In the step of cartridge 4, when filling head 12 in dipping and shutter elements 21 when in an open position, the air be contained in but fluid food flows through passage 50' in container 4 flows through passage 42' and arrives bleed-off passage 39b.

Thus, when completing the filling of container 4, but the first axial end portion of section 45' contacts with the fluid food in container 4.

Particularly, but the also side surface of contacting container 4 of the goods that the structure of passage 50' allows even unusual viscous, thus optimized the filling of container 4.

In view of the analysis of the feature of the fillup valve 10 to manufactured according to the present invention, 10', it allows the advantage obtained is apparent.

Particularly, but fillup valve 10,10' make that stower 1 was both treated the temperature of fluid food in the step of cartridge 4 in filling, also this has alerting ability aspect two especially in the size of the neck 6 for the treatment of cartridge 4.

In fact, the fact of carrying by flange 20,20' by distributing box 40,40', both can be according to " non-contact type " but pattern to the fluid food under container 4 filling room temperatures, can adopt same supply head 12 to the food under container 4 filling high temperature according to " contact " pattern again.

In fact, but when must be to the fluid food under container 4 filling room temperatures, distributing box 40 be fixed to flange 20.In this case, according to " non-contact type " pattern cartridge 4.

Differently, but when must be to the fluid food under container 4 filling high temperature, distributing box 40' be fixed to flange 20'.In this case, according to " contact " pattern cartridge 4.

In addition, identical filling head 12 can be there is to the container 4 of different size and heteroid neck 6 for filling.

For this reason, will with size be suitable for cartridge 4 distributing box 40, the flange 20 of 40', 20' is arranged on filling head 12 is enough to.

Finally, but the structure of sieve aperture 45 allows the enough homogeneities that keep fluid food to flow in the step of cartridge 4, and allows just after shutter elements 21 arrives off position, surface article to be captured in sieve aperture 45.

Finally, obviously can fillup valve 10,10' not deviated from modification and the modification of claim protection domain.

Particularly, flange 20 can be only spaced apartly around neck 6 and the non-aligned wherein heart.
