This invention relates to a Stirling engine as a refrigerating machine or heat pump having improved heat transfer to the working gas or improved heat transfer from the working gas of the Stirling engine to a cooling medium with simultaneous reduction of the dead space in the engine. The Stirling engine operates with injection or atomisation of a heat transfer fluid into the working spaces of the engine, due to which the heat transfer between the heat transfer medium and the working gas is improved.

A Stirling engine consisting of at least one working space (12), a cold space (11), a diaphragm or a piston (8) with an attached transmission (10), optionally a regenerator (17) between the working space (12) and the cold space (11), and optionally overflow lines (15; 16) which connect the working space (12), the cold space (11) and optionally the regenerator (17) to each other, wherein silicone oil heat transfer fluid is injected through a capillary nozzle or a hollow-cone nozzle into at least one of the spaces (11; 12) for heat exchange between the respective working gas of the spaces (11; 12) and a heat transfer fluid (32), said heat transfer fluid being atomized on injection, and wherein at least one separator (28; 29) for the heat transfer fluid (32) is provided on at least one of the spaces (11) or (12) or is connected into the overflow line (15; 16) which is optionally present, and wherein the heat transfer fluid (32) separated from the working gas is fed in circulation from the separator (28; 29) to the injection of heat transfer fluid (18; 19) again via a heat exchanger (24; 25) and a pump (22; 23).
