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. The housing is formed to include a passageway containing the pressure-relief valve therein and defines an annular space around the pressure-relief valve, between the pressure-relief valve and the housing, and with a coiled compression spring positioned in the annular space, the pressure-relief valve including an axially outwardly extending annular guide wall adjacent to the annular space which defines a radially inner side of the annular space, the housing further including a radially inwardly extending annular lip wherein the guide wall slidingly engages the lip of the housing to radially guide the pressure-relief valve during movement of the pressure-relief valve between the closure-sealing position and the pressure-relief position.
