Abstract
Apparatus for rapidly achieving a desired pressure level in a tire by gas flow through a port in the tire such as the valve stem including a conduit having one end for connection to a source of gas under pressure and another end for connection to the inflation port. Valves are utilized for selectively closing and opening the conduit and for venting the conduit to the atmosphere. A selector whereby a desired pressure level to be achieved within the tire is provided as is a pressure level sensor which is connected to the conduit. A control in the form of a microprocessor digitally operates the valves to thereby provide for rapid inflation of the tire inasmuch as substantially full source pressure is applied to the tire to thereby provide a high pressure differential and increased gas flow.
