<p><P>PROBLEM TO BE SOLVED: To suppress a contact between a piston and a cylinder during stopping of a Stirling engine having a structure in which a gas bearing is interposed between the piston and the cylinder. <P>SOLUTION: The Stirling engine 100 includes: a fluid passage 40 connecting a low temperature-side actuating fluid space MSL and a crankcase inner space CS; and a passage opening/closing valve 41 provided in the fluid passage 40 and opening and closing the fluid passage. In stopping of the Stirling engine 100, the passage opening/closing valve 41 enables communication through the fluid passage 40, at a region at which the piston 20 floats in the cylinder 30. This region is determined based on the pressure of an actuating fluid in the actuating fluid space MS and the rotational speed of a crankshaft 110 of the Stirling engine 100. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
