Abstract:
A purge valve for an EVAP system has a chamber including an inlet conduit for receiving fuel vapors from an EVAP canister, a first outlet conduit to the engine for the fuel vapors, and a second outlet conduit to the engine for the fuel vapors. Energizing the purge valve at a first current actuates a first armature from a closed position to an open position to open a first opening and allow fuel vapors to flow through the first outlet conduit to the engine, without actuating the second armature from a closed position. Energizing the purge valve at a second current that is greater than the first current actuates a second armature from a closed position to an open position to open the second opening and allow fuel vapors to flow through the second outlet conduit to the engine while maintaining the first armature in the fully open position.
