Abstract
Description
- This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60/724,855, filed Oct. 7, 2005, which is expressly incorporated by reference herein.
- The present disclosure relates to a fuel system, and particularly to a fuel-delivery control system. More particularly, the present disclosure relates to a fuel tank valve apparatus comprising a fuel tank filler neck and an inlet check valve for regulating flow of liquid fuel and fuel vapor through the fuel tank filler neck.
- A filler neck is a tube which conducts liquid fuel from a fuel-dispensing pump nozzle to an interior fuel storage region in a fuel tank. Although an open passageway through the filler neck into the fuel tank is needed during refueling to conduct liquid fuel from a pump nozzle into the fuel tank, it is desirable to close the filler neck at all other times to block discharge of liquid fuel and fuel vapor from the fuel tank through the filler neck. In many cases, a fuel cap is mounted on an outer end of the filler neck to close the filler neck during the time period before and after each tank refueling activity.
- It is also known to use a check valve with a fuel tank inlet neck to close the filler neck under certain circumstances. Inlet check valves for fuel systems are disclosed, for example, in U.S. Pat. Nos. 5,568,828 to Harris and 6,502,607 to Brown et al. and U.S. Publication No. 2005/0211311 to Gamble, which references are hereby incorporated by reference herein.
- According to the present disclosure, a fuel tank valve apparatus includes a fuel conductor mounted to a fuel tank to extend into an interior region of the fuel tank. The fuel conductor is configured to mate with an outlet end of a fuel tank filler neck. The fuel conductor includes a fuel-transfer tube and a normally closed inlet check valve coupled to a downstream end of the fuel-transfer tube.
- In illustrative embodiments, the inlet check valve is configured to include a fuel-discharge aperture that opens automatically as liquid fuel passes from the fuel tank filler neck into and through the fuel-transfer tube during fuel tank refueling so that such liquid fuel can flow into a liquid fuel reservoir provided in the interior region of the fuel tank. The fuel-discharge aperture formed in the inlet check valve closes automatically once the flow of liquid fuel discharged into the fuel tank filler neck is stopped. The inlet check valve is made of an elastic deformable material and configured to open when exposed to valve-deformation forces applied by liquid fuel moving in a liquid-conducting passageway formed in the fuel-transfer tube and the inlet check valve.
- Additional features of this disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

fuel system 10 for use with a vehicle is shown inFIGS. 1 and 2 .Fuel system 10 includes a fuel-transfer system 12 including. afiller neck 14 and afuel conductor 16 coupled tofiller neck 14.Fuel conductor 16 is coupled tofuel tank 18 in a vertical first position inFIG. 1 and in an alternative horizontal second position inFIG. 2 .Fuel conductor 16 is arranged to intercept liquid fuel flowing throughfiller neck 14 into aninterior region 20 offuel tank 18.Fuel conductor 16 is configured to regulate flow of liquid fuel and fuel vapor betweenfiller neck 14 andinterior region 20 offuel tank 18. An illustrativesecond fuel conductor 216 is shown inFIGS. 8-10 , an illustrativethird fuel conductor 316 is shown inFIGS. 11 and 12 , an illustrativefourth fuel conductor 416 is shown inFIGS. 1-15 , an illustrativefifth fuel conductor 516 is shown inFIGS. 16 and 17 , an illustrative sixth fuel conductor 616 is shown inFIGS. 18 and 19 , and an illustrative seventh fuel conductor 716 is shown inFIG. 20 . -
Fuel conductor 16 includes aninlet check valve 24 that moves (e.g., deforms) to assume an “opened” state as shown, for example, inFIGS. 6 and 7 , wheneverliquid fuel 26 is flowing throughfiller neck 14 andfuel conductor 16 during fuel tank refueling as suggested inFIG. 1 .Inlet check valve 24 provides an “inlet” for liquid fuel flowing intointerior region 20 offuel tank 18 during tank refueling as suggested inFIG. 1 .Inlet check valve 24 moves normally to assume a “closed” state as shown, for example, inFIGS. 3 and 4 , before and after fuel tank refueling as suggested inFIG. 2 . As suggested diagrammatically inFIG. 2A , it is within the scope of the present disclosure to locatefuel conductor 16 outside offuel tank 18 at any suitable location (e.g., 16′, 16″, or 16′″) insidefiller neck 14 and to provide aclosure 114 forfiller neck 14, whichclosure 114 is either a filler neck cap or a “capless” filler neck closure valve mechanism of any suitable design. -
Fuel tank 18 includes atop wall 28, abottom wall 30 spaced apart fromtop wall 28, and fourside walls FIG. 1 . In one embodiment,fuel conductor 16 is arranged to extend vertically through anaperture 35 formed intop wall 28 as shown inFIG. 1 . In another embodiment,fuel conductor 16 is arranged to extend horizontally through an aperture 36 formed inside wall 31 as shown inFIG. 2 . -
Filler neck 14 includes amouth 38 at an outer end and adischarge outlet 40 at an inner end as shown, for example, inFIGS. 1 and 2 . Anouter end 42 offuel conductor 16 is coupled todischarge outlet 40 offiller neck 14.Mouth 38 offiller neck 14 is formed to receive a fuel-dispensingpump nozzle 44 coupled to afuel supply 45 during tank refueling as shown, for example, inFIG. 1 , and aclosure cap 46 at all times other than refueling as shown, for example, inFIG. 2 . - During tank refueling,
liquid fuel 26 flows throughfiller neck 14 andfuel conductor 16 and applies forces to inletcheck valve 24 sufficient to deform elastic material defininginlet check valve 24 to “open”inlet check valve 24 so thatliquid fuel 26 is discharged fromfuel conductor 16 intointerior region 20 offuel tank 18. Once tank refueling has ended, and no moreliquid fuel 26 is flowing throughfiller neck 14 andconductor 16, all of the “valve-deformation” forces generated by flowingliquid fuel 26 “disappear” and the elastic material defininginlet check valve 24 contracts or otherwise recovers to resume its normal state to “close”inlet check valve 24. Once closed, liquid fuel and fuel vapor extant ininterior region 20 offuel tank 18 are not able to escape to the surroundings throughfuel conductor 16 andfiller neck 14. Either fluorosilicone, fluorocarbon, nitrile, or some other suitable flexible material may be used to provide the elastic material ininlet check valve 24. -

An upstream end of fuel-transfer tube 50 is formed to provide a spud 56 located atouter end 42 offuel conductor 16 and adapted to be coupled to dischargeoutlet 40 offiller neck 14. In the embodiment shown inFIGS. 3 and 5 , a monolithic base made of a plastics material is configured to provide fuel-transfer tube 50,mount flange 54, and spud 56. - When installed on
fuel tank 18 as suggested, for example, inFIG. 1 , fuel-transfer tube 50 passes throughaperture 35 formed intop wall 28 offuel tank 18 to locateinlet check valve 24 ininterior region 20 offuel tank 18 and mountflange 18 mates withtop wall 28 to anchorfuel conductor 16 in a fixed location relative tofuel tank 18 so thatspud 56 lies outside ofinterior region 20 offuel tank 18 and mates withdischarge outlet 40 offiller neck 14. -
