Abstract
Preferably, an embodiment of a tire inflation system includes at least an axle housing a pressurized fluid, a hubcap supported by the axle and having an interior and an exterior, and a rotary union axially aligned with the axle and mounted to the hubcap from the exterior of the hubcap. The rotary union preferably includes at least a rotating portion and a non-rotating portion, the rotating portion rotates with hub cap, and the non-rotating portion including at least a fluid conduit defining an air passage there through. The air conduit is preferably in fluid communication with the source of pressurized air, and is preferably configured for conducting pressurized air from said source of pressurized air to a tire mounted to the wheel of the vehicle, and for developing a dynamic seal between the fluid conduit and the rotating portion.
