Abstract

A Stirling engine which utilizes an inner and outer dual shell pressure containment system surrounding the high pressure and temperature engine components. The space between the shells is filled with a pressure backup gas and an insulation material with the backup gas being in communications with the working fluid. The backup gas and insulation provide a time varying pressure field, driven by the pressure variations in the Stirling engine working fluid, which cancels the pressure differential on the heat transfer tubing and allows an averaging of pressures during each cycle of engine operation. In one embodiment the backup gas is placed inside the inner shell.
