ABSTRACT:
The present invention relates to a Stirling engine which includes a first wall member forming a part of a vessel, a second wall member forming a part of the vessel, a third wall member forming a part of the vessel which is transformable and at the same time the transformation of which can change the positional relationship of the second wall member relative to the first wall member, a working fluid sealed in the vessel, a heater for heating the working fluid in the vessel through the first wall member, a cooler for cooling the working fluid in the vessel through the second wall member, a regenerator and a mechanical device which is driven by the working fluid when the working fluid is moved relative to the second wall member to change the pressure so that a part of the heat generated by the heater and transferred to the working fluid is used for driving the mechanical device. The first and second wall members are not connected by a bolt and a nut as in the prior art, but are connected to each other, for example, by bellows. Therefore, according to the present invention, the heat lost from the first wall member to the second wall member is reduced to enhance the thernal efficiency of the Stirling engine.
