PURPOSE:To enable smooth moving in and out of blades, by a method wherein a combustion gas or a steam pressure is exerted on blades, and the blades are moved in and out by means of a grooved cam. CONSTITUTION:A groove is formed in the outer periphery of a columnar rotor 4, and flat type blades 2 are slid in the groove. Sliders 3 attached to both sides of the blade 2 are fit in grooved cams 1 formed in both inner side surfaces, and the blades 2, rotated not along with rotation of the rotor 4, are moved in and out from the groove. A mechanism producing a rotation motive power is constituted such that pressure fluid, flowing through a nozzle port 6, is exerted on the blades at a portion extended between P and Q, where the blade 2 is moved out from the groove and is brought into contact with the inner surface of a casing 5, and the rotor 4 is rotated to produce a motive power. This enables the blades to be smoothly moved in and out by means of the grooved cam with the aid of a blade type rotary mechanism which creates rotational movement or functions as a pump by circumferentially exerting pressure fluid. |
