US Classification:

152416

Abstract:

A vehicle air system (300) for a vehicle equipped with a source of pressurized fluid (302, 306), an air brake system (314), a central tire inflation system (316) and a central tire inflation system pressurized fluid reservoir (336) is provided. Preferably, the central tire inflation system reservoir is defined in part by the vehicle spare tire. The central tire inflation system rservoir is fluidly connected to the source of pressurized fluid, the vehicle air brake system and the central tire inflation system by a pair of parallel conduits (332, 334), one of which is provided with a one way check valve (340) allowing pressurized fluid stored in the reservoir to be supplied to the brake system of the central tire inflation system.

Abstract:

A tire valve assembly (300) for a central tire inflation system (10) comprising a single valve body (302) having only a first (304) and a second (306) fluid connection from the exterior to the interior thereof is provided. The first fluid connection comprises a first port (304) connected to a selectively pressurized and exhausted conduit (52) and the second fluid connection comprises a second port (306) connected to the interior pressurized chamber (74) of an inflatable tire (12). The assembly includes first valve means (314) responsive to pressurization and exhausting of said selectively pressurized and exhausted conduit to establish or block, respectively, fluid communication between said first and second ports and second valve means (316) responsive to pressurization in said interior tire chamber to maintain said first valve means in the closed position thereof if said interior tire chamber is pressurized below a predetermined reference pressure. As the valve assembly is provided in a single valve body and requires no venting to atmosphere other than through the first port (304), the valve assembly may be mounted within the interior pressurized tire chamber (74) such as within a pocket (404) provided in an annular sleeve type bead lock (400).
