<p>PROBLEM TO BE SOLVED: To provide a Stirling engine capable of adjusting a heating temperature and a heat exchange amount by using a heating element variable in the heating temperature on the basis of a surface area and voltage.SOLUTION: A Stirling engine has a displacer piston and a power piston, and one of the spaces separated by the displacer piston serves as a high-temperature space, and the another space serves as a low-temperature space. A heating portion 5, a regenerating portion 6 and a cooling portion 7 are disposed between the high-temperature space and the low-temperature space, and a working gas is moved between the high-temperature space and the low-temperature space. A heat source cap 20 is disposed to cover the heating portion 5, a plurality of flat heating elements 30 different in the heating temperatures under the same input voltage, according to a length and a width between electrode terminals 30a, 30b are disposed on an inner peripheral face of the heat source cap 20, and the heating elements 30 are electrically connected in parallel with each other.</p> |
