Abstract:
1. A canister purge valve for regulating a fuel vapor flow between a fuel vapor collection canister and an intake manifold of an intake manifold of an internal combustion engine, the canister purge valve comprising: a body having a passage extending between a first port and a second port, the first port being adapted to be in fluid communication with the fuel vapor collection canister, and the second port being adapted to be in fluid communication with the intake manifold of the internal combustion engine; a seat defining a portion of the passage; a member movable with respect to the seat, the member moving generally along an axis to regulate the fuel vapor flow between a first configuration prohibiting fuel vapor flow through the seat and a second configuration permitting fuel vapor flow through the seat; and an actuator moving the member from the first configuration to the second configuration, the actuator including a piezo-electric element.
