Stirling engine with injection of heat transfer medium

摘要

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.
