SINGLE POINT INFLATION SYSTEM FOR TIRE CHANGER

摘要

A wheel servicing machine includes an inflation apparatus for sealing or seating a tire bead on a wheel rim. The inflation apparatus includes a nozzle with an orifice operable to emit a jet of compressed gas toward the interface of the tire bead and wheel rim when the wheel rim is mounted on a wheel holder. The nozzle is positioned such that the jet of compressed gas may interchangeably engage the tire and wheel rim interfaces on different-sized wheel and tire combinations when placed on the wheel holder, without repositioning the nozzle. The nozzle may be used with two or more different-sized wheel rim and tire combinations without changing the nozzle location. The wheel servicing machine may also include a tire changing machine, and the nozzle may be fixed to a base on the tire changing machine.
