ABSTRACT:
A normally closed wheel valve for maintaining an existing air pressure in a tire of a vehicle having a system for inflating and deflating the tire is mounted on the outer end of the wheel hub for rotation therewith and is connected in communication with a source of air under pressure on the vehicle through a coupling on the outer end of the valve which is rotatable relative thereto. The valve comprises axially opposed pneumatically actuated diaphragm elements for controlling the flow of air to and from a pair of tires rotatably mounted on a common axle of the vehicle.
