Abstract
A Stirling engine which has an expansion cylinder and a compression cylinder with an expansion piston and a compression piston, respectively, that have a fixed phase difference between them, where the expansion cylinder and the compression cylinder are connected through a heater, a regenerator, and a cooler, a fixed amount of working fluid is sealed in the expansion cylinder and a compression cylinder, and the engine is driven by heating or cooling the working fluid with the heater or the cooler, and in the above Stirling engine, the heater for heating the working fluid includes a combustion chamber attached to the expansion cylinder, a burner for jetting a combustible substance into the combustion chamber, a plurality of heat exchanger pipes for forming a plurality of passages for the working fluid to connect through between the expansion cylinder and the regenerator by turning back on themselves, in order to heat the working fluid with the high temperature gas from the burner, and a cylinder head for installing the plurality of heat exchanger pipes, in a concentric configuration with approximately equal distance apart and with an inclination of predetermined angle, on the expansi…
