ABSTRACT:
The motor comprises a casing defining a circular cavity in which a rotor is rotatably mounted. The rotor is keyed to a hollow shaft issuing from the casing. A pair of angularly-spaced radial partitions are fixed to the casing, extend across the cavity and are in sealing engagement with the rotor. The partitions define a compressor chamber and a work chamber. A hollow compressor piston and a work piston are fixed to the rotor at angularly-spaced locations and extend within and are in sweeping engagement with the compressor and work chambers, respectively. The compressor piston communicates with atmospheric air through the hollow of the shaft. A pair of valved air inlet ports open in the compressor chamber adjacent to respective partitions for adjusting the amount of air entering the latter chamber. An outlet port opens in the work chamber intermediate the partitions.
