Abstract

A rotary vane air motor housing assembly comprises a U-shaped stator housing and an end cap. The U-shaped stator housing extends from a first axial end to a second axial end. The U-shaped stator housing comprises an annular portion and an end wall portion. The annular portion comprises a cylindrical outer surface having a first center axis, and a cylindrical inner surface having a second center axis offset from the first center axis. The cylindrical inner surface defines a rotor pocket for receiving a rotor vane assembly. The end wall portion integrally joins the cylindrical outer surface to the cylindrical inner surface at the first axial end to close off a first end of the rotor pocket. The end cap is mechanically fastened to the second axial end of the U-shaped stator housing to close off a second end of the rotor pocket.
