JET STEAM ENGINE

摘要

In a steam engine which jets liquid and steam and in reaction thereto, rotates a rotor, the rotor has a well-balanced simple structure. In the steam engine, a rotor (5) having bent flow paths (53A-53D) disposed at even intervals is rotatably supported in a closed container (1) filled with the liquid while being fitted in a boss section (11) of the closed container (1). In the boss section (11), sliding contact portions (11A) each having a steam supply port and recessed portions (11B) are alternately formed. The liquid in the flow path is jetted outward by the steam supplied from the steam supply port into the bent flow path (53) to rotate the rotor (5). Since the rotor (5) has a point-symmetric shape in a cross section, there is no unbalanced weight, and the rotor has a simple structure with no movable component or the like. When the bent flow path (53) communicates with the recessed portion (11B), the remaining steam in the flow path disappears by being cooled, and thus the flow path is filled with the liquid.
