ABSTRACT:
A rolling rotor motor/compressor has a stator/cylinder with an internal rotor/piston. The stator/cylinder and rotor/piston together define a chamber and a vane extends into this chamber when the device is compressor. The rotor/piston has a pair of axially extending shafts and a pair of counterweights coact with the shafts for balancing while permitting radial movement of the rotor/piston within the stator/cylinder. This permits unloading of the compressor such as when there is a liquid slug.
