Abstract
Solenoid operated fluid control 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, a valve member for controlling fluid flow to a fluid passage, an actuator pin disposed between the armature and the valve member for moving the valve member in response to armature movement, and one or more features including an armature damping member, tubular actuator pin support body, flow diverter, coil bobbin support sleeve, and/or internal particle gettering magnet to improve valve operation.
Claims6
Solenoid operated fluid control valve, comprising a solenoid coil residing on a coil bobbin, an armature movable in response to electrical current applied to the solenoid coil, a permanent magnet, a flux washer, and a tubular sleeve radially disposed between the coil bobbin and the armature, and axially disposed between the permanent magnet and the flux washer, wherein the tubular sleeve axially abuts the permanent magnet and the flux washer.
