Isothermal Positive Displacement Machinery Abstract Positive displacement isothermal gas cycle machinery is designed with explicit control of the heat flow between the gas, the walls of the chamber and a thermal reservoir externally of the chamber. The control is achieved by providing a large chamber wall area to chamber volume ratio through the use of bellows-like walls having a configuration that ensures during each stroke numerous heat exchanges between the working gas and the bellows-like walls. The machinery includes Stirling cycle heat pumps and motors and isothermal compressors. Significant gains in thermal efficiency, up to a factor of 2, are attain- able because the largest inefficiency in all isothermal machinery is imperfect control of heat flow. A regenerator for the isothermal machinery minimizes cycle losses due to gas transfer friction, gas thermal conduction, dead volume, regenerator heat mass, regenerator heat mass thermal skin depth, and regenera- tor mass thermal conductivity in the gas flow direction.
