ABSTRACT:
A rolling rotor motor/compressor is provided with an external rotor/piston which coacts with a bore/cylinder in the housing and one or more vanes to define a rolling piston compressor. Thus, the stator does not form a part of the compression chamber. The compressor can be readily designed for two cylinder or two stage operation.
