<p>A conservative force,F(z),coupled to the piston (50) of a reciprocating-piston engine, refrigerator, or compressor acts to counter the pressure force, F<SUB>0</SUB>, on the piston (50) 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.</p> |
