PURPOSE:To miniaturize a starting device by providing a permanent magnet on a shaft below a compressor piston and providing an armature on its outer periphery forming a linear motor in a Stirling engine in which an output piston is directly connected to a compressor piston. CONSTITUTION:An operating gas in an expansion space 18 is reciprocatingly moved between the upper chamber and the lower chamber of a displacer 6 through a heater 3, a regenerator 4, and a cooler 5. A shaft on the bottom end of the displacer 6 is reciprocated in the gas spring space 8 of an output piston 7. The output piston 7 is connected to a compressor piston 11 on the lower part by means of a shaft 10, and a shaft 12 is provided on the lower part of the compressor piston 11. A permanent magnet 16 is provided on the lower end of the shaft 12, and an armature 17 is provided on its outer periphery forming a linear motor. When an engine is started, the armature 17 is electrified driving the linear motor, and the output piston is reciprocated to start the engine. |
