In a stirling engine (40) which has an expansion cylinder (42) and a compression cylinder (44) with an expansion piston (46) and a compression piston (48), respectively, that have a fixed phase difference between them, where the expansion cylinder (42) and the compression cylinder (44) are connected through a heater (58), a regenerator (52), and a cooler (50), a fixed amount of working fluid is sealed in the expansion cylinder (42) and the compression cylinder (44), and the engine is driven by heating or cooling the working fluid with the heater (58) or the cooler (50), and the heater (58) for heating the working fluid includes a combustion chamber (62) attached to the expansion cylinder (42), a burner (98) for jetting a combustible substance into the combustion chamber (62), a plurality of heat exchanger pipes (66) for forming a plurality of passages for the working fluid to connect through between the expansion cylinder (42) and the regenerator (52) by turning back on themselves, in order to heat the working fluid with the high temperature gas from the burner (98), and a cylinder head (64) for installing the plurality of heat exchanger pipes (66), in a concentric configuration with approximately equal distance apart and with an inclination of predetermined angle, on the expansion cylinder (42), in order to make equal the lengths of the passages for the working fluid between the expansion cylinder (42) and the regenerator (52). |
