摘要： A thermodynamic system for powering a reciprocating device includes a refrigerant passing in a closed loop between a refrigerant compressor, a condenser, an expansion valve, and an evaporator. The system includes a heat source for heating the refrigerant, and an engine for receiving the heated refrigerant. The engine includes a housing, a shaft axially movable within the housing, a piston attached to the shaft, a shifter for reversing piston direction, and porting for passing the refrigerant into and out of the engine housing.
