ABSTRACT A Stirling device or the like is physically arranged to both significantly reduce its size and weight relative to earlier designs as well as reduce fluid leakage into or out of the device's gas enclosure. Size and weight reduction, as well as the elimination of fluid leakage, is achieved in several ways including that of moving the counterpart to the conventional Stirling crankshaft from outside of the working-gas enclosure to inside the working- gas enclosure. In several embodiments of the invention, this rearrangement simultaneously eliminates a major source of fluid leakage. In some designs of this disclosure, the Stirling working-gas enclosure, which consists of a power piston and cylinder, are replaced by a somewhat different appearing and thoroughly sealed working-gas enclosure that includes a bellows, this also assisting in reducing weight. The Stirling displacer piston can also be modified, if desired, to direct the entrapped gas along different paths or routes depending on whether it is moving toward the expansion space or toward the compression space of the gas enclosure.
