Abstract
A vent-valve assembly is provided for use in a filler neck fuel cap. The vent-valve assembly includes a valve housing, a vacuum-relief valve subassembly which is spring-biased within the housing to channel ambient air and fuel vapor through the valve housing, and a pressure-relief valve subassembly which rides upon the vacuum-relief valve subassembly. The vacuum-relief valve subassembly includes a vacuum-relief spring and a vacuum-relief valve. The vacuum-relief valve has a valve member which rests upon the vacuum-relief spring and guide legs which depend from the valve member around the vacuum-relief spring. Flanges or feet extend out from the guide legs and engage the valve housing when the pressure-relief valve subassembly is removed from the housing. Thus, the valve housing and vacuum-relief valve cooperate to form an easy-to-assemble, self-contained, vent-valve assembly.
