A quick release valve for a pneumatic air system has a housing with a chamber. There is an air inlet, an air outlet and an exhaust opening, all in communication with the chamber. A seal is positioned to close the exhaust opening. There is a shuttle movable within the housing chamber and having a shuttle chamber, an air inlet in communication with the shuttle chamber and air outlets communicable with the shuttle chamber. The shuttle air outlets are in communication with the housing air outlet and the shuttle air inlet is in communication with the housing air inlet. There is an elastomeric valve which controls the shuttle air outlets. The shuttle has a first position wherein housing air inlet pressure is less than housing air outlet pressure in which the elastomeric valve closes the shuttle air outlets and the housing air outlet is in communication with the housing exhaust opening. The shuttle has a second position wherein the housing air inlet pressure is greater than housing air outlet pressure in which the shuttle and the seal close the exhaust opening and the housing air inlet/outlet pressure differential causes the elastomeric valve to open, permitting air to flow from the housing air inlet, through the shuttle air inlet, shuttle chamber and shuttle air outlets to the housing air outlet.

A quick release valve for a pneumatic air system includes: a housing, a chamber in said housing, an air inlet opening into said chamber, an air outlet opening into said chamber, an exhaust opening communicating with said chamber and a seal positioned to close said exhaust opening, a shuttle movable within said housing chamber and having a shuttle chamber and an air inlet connecting said housing air inlet and said shuttle chamber, shuttle air outlets positioned circumferentially about said shuttle and communicable between said shuttle chamber and housing air outlets, and an elastomeric valve member positioned about said shuttle and masking said shuttle air outlets to control the opening thereof, said shuttle having a first position wherein housing air inlet pressure is less than housing air outlet pressure in which said elastomeric valve member closes said shuttle air outlets and said housing air outlet is in communication with said housing exhaust opening, said shuttle having a second position wherein housing air inlet pressure is greater than housing air outlet pressure in which said shuttle and seal close said exhaust opening and the housing inlet/outlet pressure differential causes said elastomeric valve member to permit air to flow from said housing air inlet, through said shuttle air inlet, shuttle chamber and shuttle air outlets to said housing air outlet.
