Abstract
A free-piston type stirling engineincludes a power pistonwhich partitions the inside of a caseinto a work spaceand a bounce space, a displacer, a communication holeprovided in the power piston, a displacer rodextending from the displacerand passing through the communication hole, a first displacer supporting springelastically supporting the displacer rodat its proximal end, and a second displacer supporting springelastically supporting the displacer rodat its distal end. The power pistonand the displacerreciprocate along a central axis X of the casewith a phase difference therebetween by expansion and compression of a working gas in the work space, and bias forces of the first displacer supporting springand the second displacer supporting springrestrict tilting of the displacerand the displacer rodwith respect to the central axis X.
