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.

Pressure controlled and pressure control valve for an inflatable object

A pressure controlled valve having a housing with a first pressure chamber for communication to a pneumatically pressurized control source. The housing has an inlet for communication with a pneumatic supply source and outlet selectively in fluid flow with the inlet. A movable valve selectively opens and closes with respect to a valve seat for selectively opening a pathway from the inlet to the outlet and closing the pathway between the inlet and outlet. The pressure chamber may be sealingly and fluidly separated from the pathway between the inlet and the outlet. The pressure chamber provides a closing biasing force on the movable valve and a resilient spring mounted in the housing provides an opening biasing force on the movable valve.
