PURPOSE:To facilitate engine starting and improve engine efficiency by allowing a fan-shaped plate displacer to turn and move within a cylindrical cylinder in which a heat exchanger for heating and that for cooling are located. CONSTITUTION:A fan-shaped heating heat exchanger 31, a heat exchanger 32 for absorbing heat from working gas, a cooling heat exchanger 33, and a heat exchanger 34 connected to the heat exchanger 32 by means of a heat pipe for providing heat to the working gas are arranged on a cylindrical cylinder 2 housing a fan-shaped plate displacer piston 1. And, the displacer 1 is turned by means of an electric motor 4 to permit the working gas to move to cause heating and cooling to be repeated. A piston 5 is vertically moved depending on the magnitude of pressure changes caused by temperature changes to permit a generation coil 9 mounted on the piston 5 to yield a generated output. A proper phase difference between the piston 5 and the displacer 1 is kept by detecting the position of the piton 5 by means of sensor 7 and thereby controlling the motor 4. |
