Abstract
A quick release valve for vehicle air brake systems includes a movable valve member positioned to close upon the valve exhaust port which valve member includes a body portion and a diaphragm. The areas of the valve member exposed to the valve supply and brake ports are only slightly different in size thereby permitting operation on the valve member in response to small pressure differentials between the valve supply and brake ports.
