Abstract
A conservative force coupled to the piston of a reciprocating-piston engine, refrigerator, or compressor acts to counter the pressure force on the piston that arises from the change of volume of the working substance accompanying a change in the piston position. As a result, the efficiency of the engine, refrigerator, or compressor is improved to approach the theoretical thermodynamic limit of the underlying process.
