A Stirling engine which uses a dual pressure shell surrounding the high pressure and temperature engine components. Space between the shells is filled with an incompressible and insulating liquid material, such as a liquid salt. The liquid may have a filler material to prevent excessive movement. The liquid provides a time varying pressure field, driven by the pressure variations in the Stirling engine working fluid, which cancels the pressure differential on heat transfer tubing. The heat transfer tubing is inside of a dome which contains an incompressible, highly thermally conductive liquid, such as Sodium. The heat transfer tubing uses smaller diameter passages contained within a larger diameter body to reduce manufacturing cost and increase reliability. An annular regenerator offers improved efficiency and power levels. A throttling system vents working fluid to a low-pressure container and maintains engine efficiency. A dual chamber shaft seal prevents the escape of primary working fluid, significantly enhancing the practicality of the engine. A wobble plate attached to the crankshaft controls the displacer piston. A continuous heat extraction burner reduces flame temperature and nitrous oxide emissions from the burner. The combination described provides a Stirling engine that operates at significantly higher temperatures and pressures relative to existing technology.
