ABSTRACT:
A free-piston Stirling engine includes a hermetically sealed vessel enclosing a working space within which reciprocates a displacer. The displacer is mounted at its cold end on mounting means including a first portion, preferably a post, which reciprocates in a second portion, preferably a sleeve, fixed to the vessel. The relatively reciprocating mounting means includes a gas spring. The mounting means also reduces the effective area exposed to a pressure wave of the displacer cold end relative to the displacer hot end so that the thermodynamic system provides power by virtue of the differential areas of the displacer ends. The periodic pressure wave together with the gas spring maintain the displacer in oscillation.
