ABSTRACT:
A rotary Stirling cycle engine which has a pair of hollow chambers (20) each having an elliptical rotor (30) positioned inside and rotatably sealed to the chambers inner walls. A crankshaft (40) connects the rotors in tandem to transmit rotational energy when the rotors revolve around the chambers. A cooling and a heating heat exchanger (44) and (48) are each connected through ports (26) and (28) in the chambers sidewalls one to the other. Working fluid (60) is present at a constant volume within the chambers and heat exchangers, revolving the rotors as the volume in each chamber changes due to the cyclic expansion and contraction of the working fluid as it sweeps around the chambers through the ports while being alternately heated and cooled by the heat exchangers.
