ABSTRACT:
A proportional variable force solenoid valve for controlling the pressure of a pressurized fluid in a fluid control system in proportion to the current level of an electrical input signal comprises a movable valve for controlling the pressure of pressurized fluid in the fluid control system and a solenoid for controlling movement of the valve in linear proportion to the current level of the electrical signal. The movable valve and the solenoid are disposed in a common substantially non-magnetic housing to provide a fluid control unit. The housing may comprise an aluminum casting for insertion in an aluminum transmission body. A movable armature of the solenoid may comprise a cylindrical shaped permanent magnet, rather than a ferromagnetic armature, in order to eliminate the need for a axially magnetized permanent magnet ring. A simplified armature suspension structure, fluid diverting valve mechanism, and electromagnetic flux washer are incorporated.
