A steam engine of this invention is simply constituted and efficiently obtains mechanical energy not only from a heat source of a high temperature but also from the exhaust heat of an internal combustion engine and various kinds of heat sources of a low-temperature state such as the solar heat. In the engine, a rotor (5) comprising a folded jet pipe (51) is rotatably supported in a sealed container (1) filled with a liquid. A heating portion (9) is inserted in a center cylinder (50) at the center of the rotor, the liquid sucked through the suction pipe (52) of the rotor (5) is vaporized, and a mixture of steam and liquid is jetted from the jet pipe (51) to rotate the rotor (5). A check valve (53) for jetting and a check valve (54) for suction are disposed at the ends of the jet pipe (51) and the suction pipe (52). The jetted steam is guided to a condenser (2) disposed on the sealed container (1), and is condensed and is refluxed into the sealed container (1). A vacuum pump (23) is connected to the condenser (2), and the pressure in the sealed container is held at the saturated steam pressure. Therefore, the steam generates to rotate the rotor (5) despite the liquid has a low temperature.
