ABSTRACT:
A fuel metering device, such as a carburetor for a combustion engine, has a fuel bowl or fuel reservoir with a fuel vapor venting apparatus for, at times, venting such fuel vapors from the interior of the fuel reservoir to, for example, associated canister means. A resiliently deflectable valve member carried as by a stem of an associated solenoid assembly serves to open and close related fuel vapor vent passages. When in one of its operating positions, the valve member is effective for opening a vent passage leading to an associated canister and, when in another of its operating positions, the valve member is effective for opening a vent passage leading to a motive fluid induction passage leading to the associated combustion engine.
