ABSTRACT:
A proportional variable force solenoid valve comprises a non-magnetic housing having a solenoid and a permanent magnet armature movable by the solenoid in response to current applied to the solenoid, a coil compression spring for biasing the armature in a direction to establish a valve fluid pressure response to solenoid current, and a valve housing closure engaging the spring and permanently deformed to position the closure relative to the spring in a manner to adjust the valve response. The size of the valve is reduced by providing a permanent magnet armature of reduced length having a flat outermost axial end which is engaged by the spring. A plate spring retainer is disposed on the flat axial end of the permanent magnet armature and is received with clearance in an enlarged longitudinal bore region of the solenoid coil bobbin.
