Abstract: A rotary steam engine of a simple constitution capable of efficiently obtaining mechanical energy not only from a heat source of a high temperature but also from various heat sources in a low-temperature state such as the exhaust heat of an internal combustion engine. The engine has a rotor 1 having a plurality of displacement chambers 11 provided in a sealed container 2 which is filled with a liquid. A steam-generating portion 4 is arranged under the rotor 1 and where the liquid vaporizes being heated by the exhaust heat of an internal combustion engine. The vaporized stem is jetted from a flow-out passage 42 toward the displacement chambers 11 of the rotor 1. The steam stays in the displacement chambers 11 and, therefore, buoyancy acts onto the displacement chambers 11 on one side of the rotor 1. The rotor 1 rotates to produce the rotational energy.

In the steam engine, the rotor 5 having a plurality of bent flow paths 53A to 53D arranged at regular intervals therein is rotatably supported in a closed container 1 filled with the liquid being fitted onto a boss portion 11 of the closed container 1. The boss portion 11 is alternately forming slide-contact portions 11A having a steam feed port and recessed portions 11B.

The rotor 5 is of a point-symmetrical shape in cross section free of unbalanced weight, has no moving part, and is simple in structure. When the bent flow path 53 communicates with the recessed portion 11B, the steam remaining in the flow path is cooled and disappears, and the flow path is filled with the liquid.
