PROPORTIONAL VARIABLE FORCE SOLENOID CONTROL VALVE WITH ARMATURE DAMPING

摘要

Proportional variable force solenoid valve for controlling the pressure of a fluid in a fluid control system comprises a solenoid housing having therein a solenoid coil, an armature movable in response to electrical current applied to the solenoid coil, and a biasing spring for biasing the armature in a direction to establish a valve fluid pressure response to solenoid coil current. An inner armature end cooperates with or engages a damping member residing in a fluid damping chamber to reduce non-linear valve responses resulting from pressure oscillations in the fluid control system.
