ABSTRACT:
An electromechanical fluid control valve includes a solenoid-actuated actuating pin in a fluid passage for actuating a fluid control valve, and a spiral locating member for centering the actuating pin coaxially relative to the armature and fluid control valve. The spiral locating member may comprise a wire wound helically about the actuating pin along a portion of its length. The actuating pin is guided for movement by an inner surface of the spiral pin locating member. An outer surface of the spiral pin locating member is supported in a fluid passage of the valve to center the locating member therein between the armature and fluid control valve.
