摘要
An improved apparatus for selectively deflating and inflating a tire mounted on a wheel comprises a valve assembly rigidly and coaxially mounted on a vehicular wheel incorporating a reciprocally movable valve body received in a cavity of a valve housing, the valve body having a plurality of channels for directing gas to gas outlet ports for pressurizing the tire, the valve body moving to a first position to close off a gas exhaust port in the valve housing and a second position to open the exhaust port when pressurized gas to the valve from a pressurized gas source is terminated. The valve assembly includes a valve member movably secured on the valve body alternately opening and closing the gas directing channels as the valve body is moved between the first and second positions. In a driver education system additional power steering and power brake failure assemblies are incorporated.
