ABSTRACT:
A purge valve includes an aperture, a member, and an actuator. The aperture defines a portion of a vapor flow path that extends between a first port that communicates vapor with a fuel vapor collection canister and a second port that communicates vapor with an intake manifold. The member is displaced with respect to the aperture between a first configuration wherein the member occludes the aperture and a second configuration that permits vapor flow along the vapor flow path. The actuator displaces the member between the first and second configurations and includes an armature and a stator. The stator includes a winding that extends along an axis. And the armature, which is coupled to the member, surrounds the winding and includes a permanent magnet.
