A rotary air motor has a liner disposed within a tool housing and having a cylindrical bore therethrough. A rotor having radially slidable vanes is eccentrically rotatably mounted in the bore by bearings in the plates of the liner, the vanes cooperating with the rotor and the liner to define a plurality of rotating variable volume fluid compartments. A fluid inlet port in one end plate communicates sequentially with the fluid compartments. First and second exhaust ports respectively formed in the end plates also communicate sequentially with the fluid compartments, but the two exhaust ports are angularly offset from each other so that the fluid compartments communicate first with the exhaust port remote from the entry end plate and then with the exhaust port at the entry end plate. The exhaust passage from the remote exhaust port passes along the outside of the liner back to the entry end plate, thereby ensuring cooling of both ends of the motor.
In a fluid operated rotary motor including a liner having a cylindrical bore therethrough, a rotor having radially slidable vanes and being eccentrically mounted in the cylindrical bore, first and second end plates respectively mounted at first and second ends of the liner and rotatably supporting the rotor, and a fluid inlet port communicating with the interior of the cylindrical bore adjacent to the first end of the liner, the improvement comprising:
