Abstract
A steam engine in which a liquid and a steam are jetted so that a rotor is turned by the reaction thereof, and the rotor having a well-balanced simple structure. In the steam engine, the rotorhaving a plurality of bent flow pathsA toD arranged at regular intervals therein is rotatably supported in a closed containerfilled with the liquid being fitted onto a boss portionof the closed container. The boss portionis alternately forming slide-contact portionsA having a steam feed port and recessed portionsB. The steam fed into the bent flow pathfrom the steam feed port causes the liquid in the flow path to be jetted outward to rotate the rotor. The rotoris 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 pathcommunicates with the recessed portionB, the steam remaining in the flow path is cooled and disappears, and the flow path is filled with the liquid.
