ABSTRACT:
A combination seal and check valve to be mounted in a filler pipe of a fuel tank to minimize the escape of vapor from the tank when its cap is removed, typically during refueling, comprises an annular body of elastomeric material which includes an internal annular lip for sealing around the outer surface of a fuel nozzle, and an integral check valve portion at the axially inner end thereof. This check valve portion includes at least three gusset members which are of such configuration and proportions that when a fuel nozzle is inserted through the unit, the gusset members are deflected radially outwardly to open a passage through the check valve without being stretched or otherwise distorted by passage of the fuel nozzle therepast.
