ABSTRACT:
A four-way directional flow control air valve having a valve spool movable to a first position. A solenoid has a pole piece seated against the valve body adjacent one end of the valve spool. An end of the valve spool is seated against the solenoid pole piece when the valve spool is in the first position. A pusher rod on the valve spool extends through a bore in the pole piece into engagement with a solenoid armature, whereby when the solenoid is energized, the armature moves the pusher rod and the valve spool from the first position to a second position a distance equal to the difference in length between the pole piece and the pusher rod. The valve spool can be moved back alternatively by a return spring or a second solenoid engageable with the other end of the valve spool in the same manner as the first solenoid moves the valve spool to the second position.
