<p>A Stirling cycle heat engine, specially suitable for use in environments subject to acceleration or large temperature varia- ions, including a free and reciprocating displacer piston (2) fitted with a non-contact device which acts with increasing force to oppose further movement whenever the piston overshoots jesired limits of its movement. The device may include a magnet (15) which is carried by the piston shaft (10) and which experiences repulsion from like poles of magnets (16,17) carried by the shaft housing (13).</p> |
