Abstract: A filler neck closure assembly for a vehicle fuel tank filler neck, comprising: a housing configured to be mounted in the filler neck and formed to include a sealing surface and a pressure-relief valve positioned to lie in the housing and provided with a nozzle-receiving portion and a sealing portion, wherein the nozzle-receiving portion is formed to include a nozzle-receiving opening sized to receive a pump nozzle during refueling of the fuel tank and the sealing portion is movable with the nozzle portion and relative to the housing between a closure-sealing position sealingly engaging the sealing surface and a pressure-relief position away from the sealing surface to define an opening to vent fuel vapor from the fuel tank when tank pressure exceeds a predetermined maximum pressure.
Abstract: A filler neck is provided for delivering fuel in a vehicle fuel tank. The filler neck includes a conduit that formed to be coupled to a fuel tank inlet and has neck passageway. A partition unit is positioned in the conduit to divide the neck passageway into an outer chamber and an inner chamber and includes a partition channel interconnecting the outer and inner chambers. A filler neck shuttle is also positioned for movement in the neck passageway and the partition channel between a channel-opening position and a channel-closing position. The shuttle has a nozzle-receiving inlet, a fuel-discharging outlet for extension through the partition channel and into the inner chamber, and a fill passageway extending between the inlet and the outlet. Further, the filler neck includes a spring that yieldably urges the filler neck shuttle in the channel-closing position.
