Abstract: An axle assembly is provided for a tire inflation system and supports a wheel which is movably mountable on the axle. The axle assembly includes an axle housing, an axle rotatably supported by the axle housing and an end plate sealingly engaging an end of the axle. A supply passage and a pilot conduit extend axially along a central axis of the axle, and communicate supply and pilot inlets to supply and pilot outlets in the end plate. Flexible supply and pilot hoses are coiled around an outer surface of the axle and connect the outlets to an inflation control valve mounted to a hub of the wheel. The supply passage and pilot conduit are coaxial and the pilot conduit extends through the supply passage.
