Variable-volume rotating fluid-dynamic machine

Реферат: The machine comprises an internal cylindrical space (3), onto which there is coaxially inserted a shaft (4) on which there is rotatably mounted a succession of radial blades (6) which graze the peripheral circumference of said cylindrical space, and a rotor (9) eccentrically rotatable in said cylindrical space and provided with small circumferentially spaced rotating rollers (8), parallel to the axis of rotation of the rotor (9), each of which is slidably traversed by one of said blades (6).
