<P>PROBLEM TO BE SOLVED: To construct novel mechanism and system capable of more simplifying the mechanism and attaining high speed rotation because a Stirling engine developed from the past as an efficient heat-regenerative type external combustion engine is difficult to be speeded up due to working fluid reciprocating, solution can be expected if it is made in a rotation type (rotary type) mechanism and in a circulating motion and in a similar Ericsson cycle, connection between both isothermal (low temperature) compression and isothermal (high temperature) expansion strokes is isobaric. Ž<P>SOLUTION: A heat regenerative Ericsson cycle type heat engine is mainly constructed of a displacement type rotary isothermal compression mechanism, an electric motor driving it, a heat exchanger for heating (heater), a displacement type rotary isothermal expansion mechanism, a power take-off device or electric power generator by it, a heat exchanger for cooling (cooler), a control mechanism and the like. With the mechanisms, internally sealed fluid is sequentially isothermal-compressed, isothermal-heated, isothermal-expanded and isothermal-cooled to obtain shaft output. An electric motor is used for driving a compressor and the output of the expander is subjected to electric control or the like so as to be taken out by the electric power generator.
