Vehicle air system including central tire inflation system
First Claim
1. A vehicle air system for a vehicle equipped with air brakes, a central tire inflation system and a central tire inflation system pressurized fluid reservoir for storing pressurized fluid therein for charging both said vehicle air brake system and said central tire inflation system said vehicle air system comprising:
- a source of pressurized fluid;
a first conduit fluidly connected to said source;
a second fluid conduit fluidly connecting said first conduit to said vehicle air brake system;
a first one-way check valve associated with said second conduit, said first one-way check valve allowing fluid to flow from said first conduit to said brake system only;
a third fluid conduit fluidly connected to said first conduit and to said central tire inflation system;
a fourth conduit fluidly connecting said third conduit to said central tire inflation system reservoir, said fourth conduit including a fluid flow restriction therein limiting the flow of fluid therethrough;
a fifth conduit fluidly connecting said third conduit to said central tire inflation system reservoir;
said fourth conduit and said fifth conduit defining parallel fluid conduit paths from said third conduit to said central tire inflation system reservoira second one-way check valve associated with said fifth conduit for controlling the flow of fluid therethrough, said second one-way check valve allowing fluid to flow from said central tire inflation system reservoir to said third conduit onlywhereby pressurized fluid stored in said central tire inflation system reservoir can charge both said central tire inflation system and said air brake system.

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.
