Abstract
Description
- This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60/536,608, filed Jan. 15, 2004, which is expressly incorporated by reference herein.
- The present disclosure relates to a filler neck closure assembly for a vehicle fuel tank, and particularly to a filler neck closure for use in a capless fuel tank filler neck. More particularly, the present disclosure relates to closure seals and to pressure/vacuum-relief valves for use in a filler neck closure assembly.
- A removable fuel cap with a sealing gasket is typically used to close the open end of a fuel tank filler neck. After an attendant fills the fuel tank and withdraws the pump nozzle from the filler neck, the fuel cap is attached to the filler neck so that the sealing gasket forms a seal between the fuel cap and the filler neck. Thus, the fuel cap closes the open end of the filler neck to block discharge of liquid fuel and fuel vapor from the fuel tank through the filler neck. Some fuel caps are provided with pressure-relief and vacuum-relief valves to permit some controlled venting of fuel vapors in the filler neck, while the fuel cap is mounted on the filler neck.
- It has been observed that fuel caps are often lost or damaged over time and, as a result, the open end of the filler neck might not be closed and sealed in accordance with original equipment specifications during operation of the vehicle. Accordingly, a filler neck configured to “open” automatically as a fuel-dispensing pump nozzle is inserted into the filler neck during refueling and “close” automatically once the pump nozzle is withdrawn from the filler neck without requiring an attendant to reattach a fuel cap to the filler neck would be an improvement over many conventional capped filler neck systems. Although conventional fuel caps function to close filler necks in a satisfactory manner, it is thought that a capless filler neck could make vehicle refueling more convenient for consumers because no action other than inserting a pump nozzle into the outer end of the filler neck would be required to begin refueling a vehicle.
- According to the present disclosure, a filler neck closure assembly includes a nozzle-receiving housing associated with a vehicle fuel tank filler neck. The assembly also includes a partition arranged to create two vent chambers in the housing and a flow control valve assembly for regulating flow of ambient air and/or fuel vapor through the vent chambers.

Base 38 ofhousing 36 includes first and second shaft mounts 285, 385 as shown, for example, inFIG. 3 . Eachshaft mount pivot shaft 185 to supportpivot shaft 185 for movement relative to shaft mounts 285, 385 as suggested, for example, inFIGS. 4-7 . - Each
shaft mount slot 400 adapted to receivepivot shaft 185 therein so as to provide a “shaft receiver.” In the illustrated embodiment,slot 400 is L-shaped and includes a horizontally extendingentry portion 401 and a vertically extending shaft-retainer portion 402 as shown, for example, inFIGS. 3-7 and 16-19. During assembly,pivot shaft 185 is moved throughentry portion 401 to reach shaft-retainer portion 402. Oncepivot shaft 185 is located in shaft-retainer portion 402,flapper door 66 can be pivoted about a longitudinal axis ofpivot shaft 185 between opened and closed positions. Vertically extending shaft-retainer portion 402 is sized and configured to allowflapper door 66 to “float” in up-and-down vertical directions so as to seal or otherwise mate properly withannular seal 65. Ease of assembly is promoted owing to the location of shaft mounts 285, 385 on the underside ofhousing 36 and accessibility of openings intoentry portions 401 formed in shaft mounts 285, 385. - Vacuum-
relief apparatus 30 includes aspring retainer 220 including afloor 222 carrying anupstanding spring post 224 and a pair of upstanding spaced-apartside walls fasteners housing 36 and depending frombottom wall 62 ofbase 38 as suggested inFIGS. 3 and 4 . A vacuum-relief valve 234 is mounted to move up and down invent passage 54 and include aseal member 236 and aseal carrier 238. Aspring 240 is positioned to lie invent passage 54 centered in part byspring post 224 to engageseal carrier 238 andfloor 222 normally to urgeseal member 236 to engage a valve seat formed onbottom wall 62 ofbase 38 to close anaperture 242 opening intoinner vent chamber 50. Funnel 164 ofpartition 44 is arranged to overlieaperture 242 to shield components included in vacuum-relief apparatus 30 from exposure to contaminants admitted inadvertently intoouter vent chamber 52. - Owing to the modularity of
partition 44,assembly 10 can be configured easily to accept small-diameter unleaded fuel-dispensing pump nozzles or larger-diameter diesel fuel-dispensing pump nozzles.Assembly 10 can be adapted to work with either style of pump nozzle by manufacturingassembly 10 to include apartition 44 configured to work with the desired style of pump nozzle. During manufacture,partition 44 is selected from a group comprising a first partition including a funnel formed to include a narrow-diameter outlet aperture associated with an unleaded fuel-dispensing pump nozzle and a second partition including a funnel formed to include a relatively larger large-diameter outlet aperture associated with a diesel fuel-dispensing pump nozzle. - As shown in
FIGS. 13-15 , filler neck closure assembly 11 includes a base 38′ welded toouter body 40′ to define a housing.Outer closure 60′ includes aseal member 61′ coupled toappearance door 59′.Flapper door 66′ is arranged to mate with first and second rings included inannular seal 65′, which seal 65′ is retained in place onbottom wall 62 byseal retainer 67′.Housing 36′ includes a base 38′ includingbottom wall 62 and alower portion 176 of a housing side wall and anouter body 40′ including anupper portion 312 of the housing side wall and avent port 314 is formed inupper portion 312 of the side wall. In the illustrated embodiment, a vertically extending shaft-retainer portion 402′ ofslot 400′ is formed inflapper door 66′ and arranged to receivepivot shaft 185. - A flow
control valve assembly 316 is configured normally to closevent port 314 to regulate pressure of air and fuel vapor inouter vent chamber 52. In the illustrated embodiment,several vent ports 314 are provided. By using flowcontrol valve assembly 316, it is possible to control and regulate pressure conditions inouter vent chamber 52 more precisely in a way that is useful in certain vehicle emission regulatory environments. - Flow
control valve assembly 316 includes an umbrella vacuum-relief valve 318 having astem 320 coupled toupper portion 312 of the side wall and avalve member 322 located ininterior region 48 ofhousing 36 and movable from a normally closed position closingvent port 314 as shown inFIGS. 13 and 15 to an opened position openingvent port 314, as shown inFIG. 14 , upon development of a negative pressure ininterior region 48 that is below a selected pressure threshold level.Upper portion 312 of the side wall is formed to include a mountinghole 324 alongsidevent port 314.Stem 320 is arranged to extend through mountinghole 324 and is formed to include a pressure-relief passageway 326 having anopening 328 formed invalve member 322. A duck-bill pressure-relief valve 330 is coupled to stem 320 and configured normally to close pressure-relief passageway 326 to block discharge of fuel vapor fromouter vent chamber 32 through pressure-relief passageway 326 until pressure of the fuel vapor extant inouter vent chamber 52 exceeds a selected threshold level. In the illustrated embodiment, flowcontrol valve assembly 316 includes a vacuum-relief valve and a pressure-relief valve. - Umbrella vacuum-
relief valve 318 is useful when used with a particular vapor-recovery fuel-dispensing pump nozzle which draws a vacuum on the filler neck while sealing the upper end. The umbrella valve provides make-up air to prevent excessive vacuum and premature nozzle shut-offs. The duck-bill pressure-relief valve 330 in the center provides a vent passage whenouter closure 60 is closed and the pressure-relief valve is activated. - Alternative annular seals and flapper door designs are shown in
FIGS. 16-19 . As suggested inFIGS. 16 and 17 ,flapper door 66″ mates with a normally unsplayedannular seal 65″ held in place byseal retainer 67″. As suggested inFIGS. 18 and 19 ,flapper door 66′″ mates with a normally splayedannular seal 65′″ held in place byseal retainer 67′″. In each case,pivot shaft 185 is retained inslots 400 formed in shaft mounts 285, 385.
