Abstract: An external combustion engine alternately repeating a first stroke of making a working fluid evaporate at a plurality of heating portions and making a liquid phase part of the working fluid displace toward an output part side and a second stroke of making the working fluid evaporated at the first stroke condense at the plurality of cooling portions and making the liquid phase part of the working fluid displace toward the side of the plurality of the heating portions and provided with inflow adjusting means for reducing differences in inflows among the plurality of the heating portions, wherein the inflow is defined as the amount of a liquid phase part of the working fluid flowing into the heating portions when the liquid phase part of the working fluid displaces from the output part side to the side of the plurality of the heating portions in the second stroke.

Abstract: An external combustion engine is disclosed, comprising a container (11) for sealing a working liquid (12) in a way adapted to allow the liquid to flow therein, a heater (13) for heating and vaporizing the working liquid (12) in the container (11), and a cooler (14) for cooling and liquefying the vapor of the working liquid (12) heated and vaporized by the heater (13). The displacement of the working liquid (12) caused by the volume change of the vapor of the working liquid (12) is output by being converted into mechanical energy. In the heated portion (11d) of the container (11) for vaporizing the working liquid (12), the direction of displacement of the working liquid (12) at the parts (17, 19) far from the cooler (14) is changed with respect to the direction of displacement at the part (16) near to the cooler (14).
