Abstract
An axial vane rotary device includes members defining an outer wing and an inner wing, both of which are affixed to the rotor for rotation therewith. The outer wing defines a surface that carries the radially outer ends of the vanes for axial movement thereon. The outer wing forms a seal between the radially outer end of the vanes and the inner face of the annular outer wall of the stator. In addition frictional wear of the vanes is substantially reduced by elimination of sliding contact between the radially outer ends of the vanes and the stationary annular outer wall of the stator. The inner wing axially slidably carries the radially inner ends of the vanes. In this manner, excessive wear on the radially outer and radially inner ends of the vanes is substantially reduced since the only frictional wear experienced by the ends of the vanes is due to the axial movement of the vanes in the rotor slots. Leakage between the inner housing and the rotor is essentially eliminated by the inner wing.
