A valve assembly used as part of a vapor purge system, which uses a vacuum created by a venturi nozzle to direct purge vapor from a canister through the purge system, and into an intake manifold. The valve assembly includes a check valve which closes the flow path to prevent the uncontrolled venting of hydrocarbon rich purge vapor directly to the atmosphere, and provides an on-board diagnostic (OBD) check to make sure the system is functioning properly. The check valve is typically open because of a pressure balance around the check valve, allowing the turbo bleed flow, as well as the purge vapor, to pass through the check valve and into an air box. If the hose is disconnected, there is a pressure drop across the valve, which causes the check valve to close, preventing the release of hydrocarbons in the purge vapor to the atmosphere.

A linear actuator includes a plastic housing having an integral flange for mounting the actuator. A stator assembly, having windings, is disposed in the plastic housing. A rotor assembly, having a permanent magnet, is mounted for rotation with respect to the stator assembly such that when the windings are energized, a magnetic field is generated to cause rotation of the rotor assembly. A shaft is restricted from rotation and is associated with the rotor assembly such that rotation of the rotor assembly causes linear movement of the shaft. Connector structure houses leads for powering the windings. The plastic housing has an annular end that captures an annular surface of the connector structure to couple the plastic housing to the connector structure.

An apparatus and method for retaining a poppet seal with respect to a housing of an integrated pressure management system. The integrated pressure management system includes an aperture near a mouth of a housing, and the mouth includes a tip that is deformable so as to retain the poppet seal in the aperture. The apparatus includes a die and a collet. The die moves along an axis, and includes a face adapted to engage the mouth. The face includes a forming-over section adapted to engage the tip. The collet surrounds the die and extends along the axis between first and second axial ends. The collet includes first and second portions. The first portion extends between the first axial end and an intermediate axial position. The second portion extends between the intermediate axial position and the second axial end, and includes a plurality of segments positioned about the axis. Each of the plurality of segments includes at the second axial end a radially inward projecting tooth, and each tooth includes a tapered face.
