Abstract

A Stirling engine has a fluid passage that connects a low temperature-side actuating fluid space and a crankcase inner space, and a passage opening/closing valve that is provided in the fluid passage and that opens and closes the fluid passage. The passage opening/closing valve enables communication through the fluid passage upon startup of the Stirling engine, and shuts off communication through the fluid passage when the rotational speed of the crankshaft of the Stirling engine is equal to or greater than a pre-established start-enabling rotational speed.
