ABSTRACT:
A heat engine having a cold compression space, a hot expansion space, a first passage connecting the two spaces through an externally heated heater and a second passage connecting the two spaces independently of the first passage through an externally cooled cooler. Preferably with the provision of intake and discharge valves, the two passages are arranged such that a working gas confined in the engine is passed from the compression space to the expansion space through the first passage and then returned to the compression space through the second passage. The engine may be combined with a gas reservoir which is equipped with valves and connected to the passages at low temperature sections for controlling the engine power by varying the mass of the working gas confined in the engine.
