Abstract: A purge valve is in fluid communication between a fuel vapor collection canister and an intake manifold of an internal combustion engine. The purge valve includes a body, a seat, a head, and a solenoid. The body defines a fuel vapor flow path between a first port is in fluid communication with the fuel vapor collection canister, and a second port is in fluid communication with the intake manifold. The seat defines an aperture through which the fluid flow passes in an open configuration of the purge valve. The head includes a permanent magnet, and is attracted to the seat and occludes the aperture in a closed configuration of the purge valve. The solenoid repels the head toward the open configuration when the solenoid is energized, and the head occludes the aperture due to the magnetic attraction with the seat when the solenoid is de-energized.

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.

And the armature, which is coupled to the member, surrounds the winding and includes a permanent magnet.

Abstract: A valve and method of purging fuel vapors from a fuel vapor collection canister. The purge valve includes an aperture, a member that is displaced between closed and open configurations with respect to the aperture, and an actuator. The actuator, which displaces the member between the configurations, includes an armature and a stator. The armature is coupled to the member, the stator includes a winding, and the actuator includes a permanent magnet. The purge valve may be directly mounted to the intake manifold of an internal combustion engine.
