Abstract: A valve assembly for the inflation of and the release of lubricant into a pneumatic tire comprises a housing incorporating a control chamber, having inlet and outlet valves, which valves are both open or shut enabling inflation, through the chamber, of said chamber and an associated tire to substantially equal pressures. The assembly includes a pressure sensitive device arranged to respond to pressure differentials between the chamber and tire to release lubricant into the tire when a predetermined pressure differential exists.
