ABSTRACT:
Drive means for the displacer piston of a free-piston Stirling type motion device comprises a rod which has one end connected to the displacer piston, while the other end, which has a small piston thereon, is mounted for limited axial movement in a cylinder zone formed in a power piston or in a stationary cylinder. A pair of gas passages connect opposite sides of the small piston to a source of compressed gas. The source of compressed gas is created by movement of the power piston.
