Patent ID: 7086383

Claim:
A purge valve in fluid communication between a fuel vapor collection canister and an intake manifold of an internal combustion engine, the purge valve comprising: a body defining a fuel vapor flow path between first and second ports, the first port being in fluid communication with the fuel vapor collection canister, and the second port being in fluid communication with the intake manifold; a seat defining an aperture through which fuel vapor flow passes in an open configuration of the purge valve, and fluid communication between the aperture and the intake manifold being prevented in a closed configuration of the purge valve; a head including a permanent magnet, the head being attracted to the seat and occluding the aperture in the closed configuration of the purge valve; and a solenoid being magnetically coupled to the head, the head being repelled by the solenoid toward the open configuration when the solenoid is energized, and the head occluding the aperture due to the magnetic attraction with the seat when the solenoid is de-energized.
