Abstract
Description
- This application is a continuation-in-part of application Ser. No. 10/417,679, filed Apr. 17, 2003, the disclosure of which is incorporated by reference herein.
- 1. Technical Field of the Invention
- The invention relates generally to safety devices in a combustible environment and more particularly to static discharge reduction between a nozzle and a static-electrical charged object.
- 2. Description of Related Art
- Fuel dispensing nozzles are well-known in the art for dispensing fuel from a fuel supply into a container. A typical example would be the fuel dispensing nozzle at a retail gasoline station wherein the dispensing nozzle is at the end of a hose connected to a dispenser which is connected to an underground storage tank. The nozzle will typically contain a valve that is actuated by the customer to dispense fuel from the underground storage tank through the dispenser, through the hose, through the nozzle and into the customer's vehicle or gasoline can.
- It is understood in the industry that dispensing volatile fuel may present a fire hazard if an ignition source is present near the dispensing nozzle. The danger is created by the fuel vapor emanating from the nozzle container interface. Therefore, it is common for fuel stations to have signs which require users to turn off their vehicles and not light cigarettes in the area of fuel dispensing to prevent such fires. Unfortunately, customers are injured from fires started by static discharge in the area immediately surrounding the nozzle.
- While each case is different, two patterns have developed where static discharge is a factor. One pattern involves fuel dispensed into a gasoline can and not the fuel tank of a vehicle. In this scenario, the can is placed on a surface that is electrically insulative, as opposed to conductive, and as the fuel is discharged from the nozzle into the can, static electricity builds up in the can. Then, as the nozzle is withdrawn from the can, the metallic highly electrically conductive nozzle spout may pass in close enough proximity to a statically-charged portion of the can to cause a static discharge between the can and the spout, which under the right conditions, can ignite the vapor in the immediate area causing a fire which can damage property and cause personal injury.
- A second scenario which has proven to cause fires in the gasoline dispensing station involves a customer locking the nozzle open while fuel is being dispensed into the vehicle fuel tank and either returning to their seat in the vehicle or going into the convenience store. The act of sliding in and out of a vehicle, or walking across a carpeted floor, can cause static electricity to build up in the customer's body. After a static charge has built up within the customer's body, a static discharge can occur between the customer and the nozzle body or other portion of the nozzle when the customer reaches down to grasp the nozzle. In such a situation, flammable vapor or fumes may have built up in the area of the nozzle such that a fire or explosion may be ignited that is capable of causing damage to property and personal injury.
- Attempts to prevent sparks in this environment include the addition of grounding straps to fuel tank filler pipes and other surfaces to prevent the build up of static electricity while filling the vehicle. Unfortunately, these grounding straps do not address the build-up of static electricity in the customer's body as they are moving across the seat of their vehicle or walking on the carpet in the convenience store, nor do they address the build-up of static discharge in a gasoline can that is placed on an insulative surface, such as a bed liner of a pickup truck. In order to address these risks, it has been known to instruct users to place gasoline cans on the ground and have users touch conductive surfaces distant from the nozzle prior to touching the nozzle end to discharge any static electricity in the customer's body.
- To the extent users do not follow the directions clearly labeled on the dispenser, the above methods do not effectively reduce the static discharge occurrence in and around the nozzle area. A system is required that would effectively eliminate static discharge in and around the nozzle area without requiring specific actions by the customer.
- An exemplary fuel dispensing nozzle includes a body, a handle connected to the body, a handle guard connected to the body and generally surrounding the handle, and a spout extending from the body. Parts of the nozzle are made of, or covered in, static dissipative materials. Additionally, an exemplary method for reducing static discharge in existing nozzle installations includes the application of static dissipative material to existing nozzles to address certain static discharge risks.

- As used herein, “static discharge” means the release of static electricity via an arc or spark between a charged object and another object. Static discharge can happen when a body comes into contact with another body at a sufficiently different potential. Electrostatic discharge can range from a voltage level just high enough to create a spark up to between 30,000-40,000 volts or higher. The actual voltage needed to create a spark depends on environmental factors, such as temperature and humidity, as well as material properties. Typically, static charge is the result of a transfer of electrons that occurs due to the sliding, rubbing or separating of a material which is a prime generator of electrostatic voltages, such as plastics, fiberglass, rubber, textiles, etc.
- As used herein, the term “static dissipative material” means materials which have a surface resistivity of between approximately 0.5 megaohms/square (0.5×106 Ohm/sq) and approximately 1,000 megaohms/square (109 Ohm/sq), plus or minus 0.2 megaohms/square (0.2×106 Ohm/sq), as measured using ASTM D257. While other materials may meet this definition, one commercially available material that may be used according the concepts described herein is sold under the tradename Stat-Kon® by LNP Engineering Plastics Inc. of Exton, Pa. Stat-Kon® is a thermoplastic composite which contains conductive additives. Other materials are within the scope of the invention. The conductive additives may be polyacrylonitrile (PAN) carbon fibers, pitch carbon fibers, Ni plated carbon fibers, stainless steel fibers, carbon powder, metal powders or aluminum flake, for example. Further discussion of such materials can be found at www.LNP.com and in particular in the brochure available therein entitled “Stat-Kon®—A guide to LNP's line of thermoplastic composites for electrostatic dissipation”, incorporated herein by reference.
- In general terms, static dissipative materials reduce the likelihood of a static discharge by increasing resistance. A highly conductive material will allow an arc while the higher resistance of the static dissipative material will discourage transfer of electrical potential until physical contact is made. This allows the potential to dissipate without encouraging an arc or static discharge. This is to be distinguished from an insulative material which may prevent immediate arcing, but does not allow the potential to dissipate, thereby allowing future discharge when a conductive material is introduced.
- As used herein, the term “structural materials” will mean materials that are not necessarily statically dissipative, but meet structural needs of a component. Structural materials would include aluminum, steel, composites, and other materials known to provide structural integrity to components manufactured thereof.
- Nozzle
- There are two major categories for fuel dispensing nozzles: vapor recovery (
FIGS. 1-4 ) and non-vapor recovery (FIGS. 5-8 ). The non-vapor recovery models are designed to dispense fuel. The vapor-recovery models are designed to dispense fuel and recover fuel vapors from the fuel container or vehicle fuel tank for environmental reasons. Of the vapor recovery variety most are vacuum assist (FIG. 14 ) or balance systems (not shown). Vacuum assist systems have a mechanism for drawing vapor from the area surrounding the nozzle, as is know in the art. According to various implementations, nozzles may be used in the transfer of fuel between a stationary fuel system, such as a pump at a gas station and a vehicle, such as a personal automobile or a fuel transportation vehicle. - Additionally or alternatively, nozzles incorporating one or various features disclosed herein may be implemented at fuel transfer stations, or in nozzles attached to fuel trucks or tankers for transfer from one tank or reservoir to another, such as a transfer of fuel from a fuel truck or tanker to a tank or reservoir of another vehicle or a refueling station.
- Balance systems use a seal between the nozzle and the fuel container or vehicle fuel tank so that as liquid fuel is pumped into the container or tank fuel vapor is pushed into the vapor recovery system. The balance system has construction that looks similar to a non-vapor recovery system, in that there are no vapor recovery holes in the nozzle spout, but includes enlarged bellows instead of a simple hood. The bellows must create a seal for the fuel to be dispensed.
- The invention described herein may be used on a non-vapor recovery nozzle, a vacuum assist vapor recovery nozzle, or balance vapor recovery nozzle, as well as other fuel dispensing nozzles. Some other nozzles may include those used to transfer fuel off of fuel delivery trucks or those used to fuel off-road vehicles, such as lawn mowers, tractors, construction equipment, airplanes, race cars, motor cycles, model cars, and other vehicles which use flammable fuels. Furthermore, the spouts are shown in standard sizes, but may be larger or smaller as the application dictates. For example, gasoline spouts in the U.S. are typically smaller than diesel spouts in the U.S. due to regulatory requirements, while in Europe there is no such distinction.
- Additionally, the features described herein may be used for applications other than fueling, when a static discharge may result in a hazardous condition. Examples of a non-fuel transfer implementation that includes the features disclosed herein may be tools for use in repairing a gas leak or for entering a building in which flammable and/or volatile chemicals or fumes may be present. Additional implementations of non-fuel transfer situations could include transferring non-flammable fluids in a flammable environment, or any other situation where static discharge could occur in a flammable environment. For example, a nozzle or other device may be required to introduce a fluid (liquid or gas) to neutralize an area contaminated with volatile and/or flammable chemicals.
- As shown in
FIGS. 1, 2 , 5, and 6, anozzle 10 includes abody 12.Body 12 is typically adapted to be attached to a hose (not shown) which supplies fuel to thenozzle 10.Body 12 may also include a hand warmer 14 as shown inFIGS. 1 and 5 .Body 12 includes avalve 16 which controls the flow of fuel through thenozzle 10. Attached to thebody 12 is ahandle 18 which controls thevalve 16 such that a consumer can adjust the amount of flow through thenozzle 10. Thehandle 18 may include a lock-open feature allowing for unattended fueling. While this feature is popular, it allows customers to return to their vehicles or enter the convenience store and develop a static charge.Nozzles 10 typically include ahandle guard 20 as shown inFIGS. 1, 2 , 5, and 6 to prevent accidental discharge of fuel. Thehandle guard 20 also allows the customer to lock thenozzle 10 open while fuel is being dispensed into the vehicle fuel tank and allows the customer to either return to the vehicle or go into the convenience store. Aspout 22 is typically attached to thebody 12 to engage a container into which thenozzle 10 transfers fuel. Thespout 22 may come in several variations as shown inFIGS. 1 through 8 . Generally, thespout 22 will include anozzle end 24 which is connected tobody 12 and a dispensingend 26 opposite thenozzle end 24. Additionally, thespout 22 will often include an automatic overflow shut offhole 28 near the dispensingend 26. Automatic shut offhole 28 is fluidly connected to a venturi valve which shuts offvalve 16 when the fuel level in a container reaches the shut offhole 28 of thespout 22. Additionally, many spouts, such as that shown inFIGS. 1, 2 , 3, and 4, will include vapor recovery holes 30. The vapor recovery holes 30 are well known in the art to provide a passage for the recovery of fuel vapors back into the fuel storage tank. Ahood 32 as shown inFIGS. 1-4 will assist in capturing vapors and reduce the chance of a consumer being splashed with fuel if they overfill the vehicle or container.Coils 34, as shown prominently inFIGS. 5, 6 , 7 and 8, and often included in vapor assist nozzles, as shown inFIGS. 1-4 , may be used to help in maintaining thespout 22 in a fuel container or fill tube of a vehicle. - In use, the
nozzle 10 is grasped about thebody 12 by a consumer who places thespout 22 into a container or fill tube of a vehicle. The consumer then grasps thehandle 18 thereby activatingvalve 16 to dispense fuel through thespout 22 into the container or fill tube of a vehicle. In typical operation, thespout 22 will come into contact with the container or fill tube of a vehicle as will thehood 32. The consumer will come into contact with at least thebody 12, or the hand warmer 14, and thehandle 18. It is also possible for the customer to grasp thenozzle 10 byhandle guard 20. - In order to effectively reduce static discharge, various parts and surfaces of
nozzle 10 must be comprised of static dissipative material. In one embodiment, all outer surfaces ofnozzle 10 will be comprised of, made from, coated with, or covered with, static dissipative material, but various combinations of surfaces can also be effective to address various issues. Additionally, total coverage of the surfaces with static dissipative material may not be necessary. For example, insulative surfaces may be combined with static dissipative surfaces and surfaces which receive exceptional wear may be coated with wear strips of structural material, whether the structural material is insulative, conductive, or dissipative. - Sleeves and Coatings
- The use of composites in this invention can be advantageous when a coating or sleeve if preferred. Such thermoplastic composites which are static dissipative may include a polymer with additives to adjust the surface resistivity of the composite. Such composites may have base resins of ABS, polystyrene, polycarbonate, polyetherimide, polyethylene, polysulfone, Nylon 11, Nylon 6/12, Nylon 6, Nylon 6/10, Nylon 6/6,
Nylon 12, polyethersulfone (PES) acetal, polyetheretherketone (PEEK), polypropylene, polyphenylene sulfide, polyurethane, polyphthalamide (PPA), super tough nylon, thermoplastic polyester (pbt), amorphous nylon, polyester elastomer, and modified polyphenylene oxide, for example. Such composites may have various additives to reduce the surface resistivity of the base resin, such as PAN carbon fibers, pitch carbon fibers, Ni plated carbon fibers, stainless steel fibers, carbon powder, metal powders, aluminum flakes, migratory antistat, and permanent antistat, for example. - One of the advantages of thermoplastic composites is that they may be formed into
sleeves 36 that conform to the shape of a structural member such as thebody 12, handle 18, handleguard 20, or spout 22, as shown inFIGS. 2 and 6 . Thesleeves 36 may includeholes 38 to align with holes in the structural member, for example, theautomatic shutoff hole 28 and vapor recovery holes 30. Additionally, thesleeve 36 may haveribs 40, which are similar in shape and size to coils 34, to maintain thespout 22 in a container. Furthermore, thesleeve 36 may be made of material that contracts when exposed to certain high temperatures so that thesleeve 36 may be secured by “heat-shrinking” thesleeve 36 onto a structural member. Alternatively, thesleeve 36 may be secured simply through an interference fit, adhesive bonding, or other acceptable means such as using a slightly elastic polymer to stretch thesleeve 36 over the structural member while maintaining static dissipative properties. - Another possible implementation when using thermoplastic composites is to coat a structural member, such as the
body 12, handle 18, handleguard 20, or spout 22, with acoating 42. One method for coating would be to coat the structural member with a molten thermoplastic composite having the desired surface resistivity. Another method would be to combine a composite with a vehicle and coat the structural member with the composite and vehicle so that when the vehicle substantially evaporates the structural member is left with coating 40 of the composite while maintaining static dissipative properties. - Structural Static Dissipative Materials
- Another advantage of composite materials is the ability to combine structural properties with static dissipative properties. By choosing more structural base composites, such as nylons or polycarbonates, along with additives that impart both strength and static dissipative properties, such as carbon fibers or steel fibers, or a mixture of strength additives and static dissipative additives, such as glass fiber with aluminum flake, a structural composite with appropriate static dissipative properties can be formed. The specific formulation will be dependent on several factors, including: the fuel the part is exposed to, if any; the stresses encountered by the part; the expected life of the part; and the amount of flexure allowed in the part. The advantages of the various ingredients is discussed in more detail in the Stat-Kon® brochure referred to above, and incorporated by reference.
- Accordingly, any of the main structural features of the nozzle, as shown in
FIGS. 1, 2 , 5, and 6, may be manufactured of structural static dissipative material, including: thebody 12; the hand warmer 14; thehandle 18; thehandle guard 20; thespout 22; thehood 32; and thecoils 34. In one embodiment of the invention thespout 22 is made of a structural dissipative material. In another embodiment, thespout 22 and thehandle 18 are each made of structural static dissipative materials. In another embodiment, thespout 22, thehandle 18, and thehandle guard 20, are each made of structural static dissipative material. In yet another embodiment, thebody 12 is made of a structural static dissipative material. In yet another embodiment, thebody 12 and thespout 22 are each made of structural static dissipative materials. In yet another embodiment thebody 12, thespout 22, and thehandle 18 are made of structural static dissipative materials. In yet another embodiment, thebody 12, thespout 22, thehandle 18, and thehandle guard 20 are comprised of a structural static dissipative material. - Spout
- Various spout designs are shown in
FIGS. 1 through 8 . Thespout 22 ofFIGS. 3 and 4 is that of a vapor assistnozzle 10 while thespout 22 of FIGS. 7 and 8 is that of ahigh flow nozzle 10. Both spouts 22 include anozzle end 24 and dispensingend 26, as well as an automatic overfill shut offhole 28. Additionally, thespout 22 ofFIGS. 3 and 4 includes vapor recovery holes 30. In order to provide static dissipative performance in cases where spout-to-can sparks may otherwise occur, thespout 22 must be comprised, at least partially, of static dissipative material. Either thespout 22 ofFIGS. 1 and 2 , or thespout 22 ofFIGS. 5 and 6 , may be comprised completely of static dissipative materials. Alternatively, thespout 22 may be comprised of structural material covered in either a sleeve of static dissipative material as shown inFIGS. 3 and 7 , or a coating of static dissipative material as shown inFIGS. 4 and 8 . The advantage of a sleeve or coating is that existing spouts may be used without having to replacespouts 22. Additionally, the sleeve or coating may allow forstronger spouts 22 where necessary. - Body
-
Body 12 is typically covered by hand warmer 14, which is typically insulative in the prior art, but may be static dissipative in accordance with the present invention. But, hand warmer 14 may be damaged thus exposingbody 12 to static discharge. Therefore,body 12 may be created entirely of a static dissipative material, or it may be coated or sleeved in a static dissipative material, similar to spout 22 discussed above. The advantage of coating orsleeving body 12 is that existingbodies 12 may be coated or sleeved for continued use. Furthermore, a coated orsleeved body 12 will give various options as to the structural material to be used below the coating or sleeve. Hand warmer 14 may be comprised of a static dissipative material. - Handle and Handle Guard
-
Handle 18 may be comprised entirely of a static dissipative material. This should not provide structural difficulties because many handle 18 currently on the market are made of insulative composites with similar structural properties to the static dissipative composites disclosed herein. If particular structural properties are desired, ahandle 18 of structural material may be coated or sleeved in a static dissipative material. Additionally, handleguard 20 may be made entirely of static dissipative material. This should not provide structural difficulties because many handleguards 20 currently on the market are made of insulative composites with similar structural properties to the static dissipative composites disclosed herein. If particular structural properties are desired, ahandle guard 20 of structural material may be coated or sleeved in static dissipative similar to spout 22 discussed above or electrically insulated from thebody 12 and handle 18. - Retrofitting and Replacement
- In addition to the novel nozzle designs mentioned above, a method for reducing static discharge in existing nozzles installations would comprise retrofitting existing nozzles with certain portions of the above designs instead of replacing the entire nozzle. In one embodiment, existing hand warmer 14 of existing
nozzle 10 is replaced with a static dissipative hand warmer 14. In another embodiment, existinghandle guard 20 of existingnozzle 10 is replaced with a staticdissipative handle guard 20. Likewise, existingspout 22, existinghandle 18, and existinghood 32, may each be replaced bystatic dissipative spout 22, handle 18, andhood 32, respectively. The replacement parts may be made of, coated with, or covered by, static dissipative materials. - Another method for reducing static discharge in existing nozzle installations would include the application of static dissipative coatings to existing nozzle parts. In one embodiment a static dissipative material is combined with a vehicle such that when the combination is viscous and may be applied to an existing part. The vehicle is then removed; for example the vehicle may evaporate at room temperature or elevated temperatures leaving the static dissipative coating. In one embodiment the combination is applied to the exterior surfaces of
nozzle 10. In another embodiment, the combination is applied to the exterior surfaces of thespout 22, as shown inFIGS. 4 and 8 . In another embodiment, the combination is applied to thespout 22 and thehandle 18. Various other exterior surfaces may be selected for particular applications. - Yet another method for reducing static discharge in existing nozzle installations would include the fitting of sleeves of static dissipative material over existing components. This could include elastomeric sleeves, friction fit sleeves, and heat shrinkable sleeves, among other designs. In one embodiment a sleeve is fitted over an existing
spout 22, as shown inFIGS. 3 and 7 . In another embodiment a sleeve is fitted over either thebody 12, thehandle 18, thespout 22, or thehandle guard 20, or a combination of these parts. The sleeve may include exterior surface features to increase the performance of the part, such asribs 40 on thespout 22, or a knurled gripping surface on thehandle 18 or thebody 12. - As various changes could be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Having thus described several embodiments of the invention, what is claimed and desired to be secured by the patent is to be found in the appended claims.
