Patent ID: 8371331

Claim:
Solenoid fluid control valve, comprising 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 wherein the actuator pin includes a tubular sleeve attached thereon and spaced from the actuator pin to form a space around the actuator pin with the space closed off at an end thereof where the sleeve is attached on the actuator pin and wherein the tubular sleeve includes an annular chamfered or radiused exhaust sealing edge at an opposite end of the space to engage a seating surface of an exhaust seat insert disposed downstream of the valve member, said seating surface extending substantially perpendicular to the longitudinal axis of the actuator pin, to close off fluid flow to an exhaust port when the armature is at an end position of the armature stroke where the valve member is unseated a maximum distance from its seat by the actuator pin.
