ABSTRACT:
A magnetically operated pressure control valve includes an electromagnetic coil having a central passage extending axially through the coil. A moveable armature is axially disposed in the coil passage to be magnetically attracted to a pole piece when the coil is energized. An armature spring biases the armature in a first position when the coil is not energized. A valve body is stationarily located in the valve housing and has two conduits therein. Movement of the armature controls fluid flow in the two conduits to control fluid flow between a supply port and a control port, and the control port and an exhaust port. Wave washer springs are located at opposite ends of the armature between the armature and the valve housing to resiliently absorb kinetic energy from movement of the armature, to reduce impact stress between the armature and housing, and to prevent a vacuum lock between the armature and housing due to their flat surfaces and the fluid in the valve.
