Vane machine with stationary and rotating cylinder parts

A vane machine used as a driving or a working machine utilising compressible or non-compressible fluids as the working media, said vane-machine comprising:

• a stationary cylinder part (A) having a shroud with working surfaces and lateral surfaces forming openings;
• two or more rotating cylinder parts (B) consisting of bearings firmly fitted into the openings of the stationary cylinder part and adjacent the shroud's working surfaces and rotate freely about a cylinder axis;
• said rotating cylinder parts and shroud working surfaces and lateral surfaces form a cylinder working chamber having cylinder ends;
• said stationary cylinder part having a plurality of radial openings letting working fluid in and out of the cylinder working chamber;
• a rotor (C) having a plurality of vanes (F) that axially rotates within the cylinder working chamber and eccentrically rotate within the shroud about shroud axes, said vanes positioned within grooves within radial surfaces of the rotor;
• at least two covers (D) positioned centrically in openings of the cylinder stationary parts, the covers have eccentric openings in which include firmly fitted bearings in which encase the rotor to enable the rotor rotational movement;
• at least two lateral plates (14) being firmly pulled over the rotor with which they rotate jointly at the same angle speed and around the same axis;
• wherein each said vanes has at least one flat upper surface (23) with longitudinal axial grooves (24) and longitudinal radial grooves (25);
• and wherein during rotation of the rotor, the flat surfaces of the vanes are affected by the centrifugal force and make contact with the bearings of the cylinder rotating parts so that the vanes are pulled into rotation;
• and the longitudinal radial grooves (25) make contact with the lateral plates (14) during rotation.
