FAST ACTING QUICK RELEASE VALVE Abstract of the Disclosure 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 shut the 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/out- let 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.
