ABSTRACT:
A high-temperature side power piston (37) and a low-temperature side power piston (39), respectively demarcating a high-temperature space (45) and a low-temperature space (47), brings about volumetric changes of working gases in each of the high-temperature space (45) and the low-temperature space (47). At the same time, the power pistons are configured to transmit motive energy on receipt of pressure changes of working gases. A displacer (203) movably housed in a displacer cylinder (201) transfers the working gases between the high-temperature space (45) and the low-temperature space (47) without causing a pressure difference.
