ABSTRACT:
In order to provide for the deflation of a tire, there is provided an orie in the rim of a wheel, a pusher element extending through the rim in a gas tight manner, the pusher element having one end communicating with gas pressure inside the tire and including means for selectively closing the orifice. The pusher element is mounted to the rim for movement between a first position wherein the means for selectively closing closes the orifice and a second position wherein the means for selectively closing opens the orifice. The pusher element has another end outside of the tire with a cam mounted thereto. A presser means mounted to be stationary relative to the rotation of the tire selectively engages the cam and moves the pusher element to the second position to control the opening of a valve to deflate the tire.
