ABSTRACT:
A tire valve assembly (56, 58) for a central tire inflation system (10) effective to automatically isolate a tire (12) pressurized to less than a predetermined minimum pressure from the remainder of the system is provided. The tire valve assembly includes a control valve (58) and a low tire pressure shut-off valve (56) which are connected to a selectively pressurized and vented conduit (52) and to a conduit (68) fluidly communicating with the interior pressurized chamber (74) of the tire. A single selectively pressurized and vented conduit (52) operates the control valve and provides the sole connection of the assembly to pressurized fluid and/or to venting to atmosphere required for system operation other than for initial inflation of the tires to the predetermined minimum pressure thereof.
