Abstract: A rotary union for a tire inflation system includes a body having a first end and a second end, the first end comprising threads for threaded coupling to a hubcap, the body forming a fluid channel extending from the first end to a surface of the body; a sleeve rotatably disposed on the body, the sleeve comprising a hose connection port, the sleeve being sealed to the body such that fluid may flow along a sealed path from the fluid channel to the hose connection; and a tubular member having a first end sealingly disposed in the fluid channel at the first end of the body.

Abstract: A rotary union is configured for removable disposition into the central bore of a hubcap through an orifice in the outboard face of the hubcap. The hubcap includes a fluid channel extending from the central bore to the exterior of the hubcap. The rotary union includes a port through which fluid may flow into the fluid channel when the rotary union is disposed in the central bore.

Abstract: A pressure equalization valve assembly may include a valve body forming fluid chamber configured to receive pressurized fluid from a fluid pressure source, a first port configured for sealed communication with a first vehicle tire, and a second port configured for sealed communication with a second vehicle tire; a first one-way valve disposed in the valve body between the fluid chamber and the first port so as to allow one-way fluid communication from the fluid chamber to the first port when the first one-way valve opens; a second one-way valve disposed in the valve body between the fluid chamber and the second port so as to allow one-way fluid communication from the fluid chamber to the second port when the second one-way valve opens; and a two-way valve disposed in the valve body between the first port and the second port so as to allow two-way fluid communication between the first port and the second port when the two-way valve opens.

Abstract: A steer axle spindle may have one or more channels formed therein. A rotary union may be mounted to a steer axle wheel end assembly. The rotary union may be sealingly connected to a pressurized fluid source through the channel, and sealingly connected to a vehicle tire.

Abstract: A rotary union for a tire inflation system may comprise a stator and a rotor assembly, and may be contained entirely within the space formed by a hubcap and wheel end. The rotor assembly may be mounted to the interior of a hubcap. The rotor assembly may comprise a tube that extends into the stator. The tube may be sealed in the rotor assembly by a first annular seal, and may be sealed in the stator by a second annular seal.
