Abstract
A pneumatic tire inflator is provided for use with a source of pressurized air and a device for controlling the flow of air therefrom. The inflator includes first and second air flow circuits, each circuit having an inlet end communicating with the downstream side of the device, and an outlet end. The first circuit is provided with a regulator having an inlet communicating with the first circuit inlet end, and an outlet. The regulator is preset whereby the air discharged from the outlet is at a predetermined tire pressure. A pressure sensitive first valve, biased to normally assume an open position, is provided having a first inlet communicating with the regulator outlet, a valve outlet, and a second inlet, the latter being segregated from the first inlet and outlet by a pressure sensitive member. The pressure sensitive member interrupts communication between the first inlet and the valve outlet when there is a predetermined pressure at said second inlet overcoming the opening bias. An air accumulator is provided in the first circuit having an inlet communicating with the outlet of the first valve. The second circuit includes a pressure sensitive second valve biased to normally ass…
