ABSTRACT:
A Stirling cycle heat engine, specially suitable for use in environments subject to acceleration or large temperature variations, including a free and reciprocating displacer piston fitted with a non-contact device which acts with increasing force to oppose further movement whenever the piston overshoots desired limits of its movement. The device may include a magnet which is carried by the piston shaft and which experiences repulsion from like poles of magnets carried by the shaft housing.
