PURGE VALVE INCLUDING A DUAL COIL ANNULAR PERMANENT MAGNET LINEAR ACTUATOR

摘要

A purge valve (200) includes an aperture (206), a member (240), and an actuator (100). The aperture (206) defines a portion of a vapor flow path that extends between a first port (202) that communicates vapor with a fuel vapor collection canister (14) and a second port (204) that communicates vapor with an intake manifold (18) of an internal combustion engine. The member (240) is displaced between a first configuration that occludes the aperture (206) and a second configuration that permits vapor flow along the vapor flow path. The actuator (100), which displaces the member (240) between the first and second configurations, includes a stator (120) and an armature (140). The stator (120) includes first and second windings (122,123) that are spaced along an axis. The armature (140), which is coupled to the member (240), includes a permanent magnet (142) that is axially positioned at least partially between the first and second windings (122,123).
