ABSTRACT:
An electromagnetically operable fluid control valve includes a valve member slidable in a bore in a valve body. Resilient means biases the valve member to the open position and an actuator including an armature when energized moves the valve member to the closed position. Stop means formed by a part movable with the armature engages the valve body to limit the movement of the armature and valve member when the actuator is de-energized. Damping means formed by a liquid filled recess in the part acts to damp the aforesaid movement.
