Abstract

An axle assembly has a fixed axle housing, a rotating axle body rotatably mounted in said axle housing, and a first chamber which surrounds the axle body. The first chamber is partially bounded by a ring member which rotates with the axle body. An annular disc is mounted on the axle body adjacent to the ring member. The disc extends radially outwardly beyond an outer rim of the ring member and radially overlaps the ring member. The disc is axially slidable towards and away from the ring member. When the disc is spaced apart from the ring member an opening or space is formed therebetween through which may be communicated pressurized air to inflate a tire. The disc is moved axially by a ring mounted on an annular piston member which is mounted on and axially movable with respect to the axle housing.
