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 of an internal combustion engine. The member is displaced between a first configuration that occludes the aperture and a second configuration that permits vapor flow along the vapor flow path. The actuator, which displaces the member between the first and second configurations, includes a stator and an armature. The stator includes first and second windings that are spaced along an axis. The armature, which is coupled to the member, includes a permanent magnet that is axially positioned at least partially between the first and second windings.
