Abstract
A pressure controlled valve assembly has a housing with a pressure controlled valve moveable between an open and closed position with respect to a valve seat for controlling communication between a pneumatic supply and a pneumatic pressure control source. The housing also has first and second passageways with a pair of check valves in each passageway. Each passageway is connectable to a reversible pump such that when the pump operates in one direction one pair of check valves allow flow while the other pair of check valves prevents backflow.
