ABSTRACT:
A vane-machine with cylinder stationary and rotating parts is intended for use as a driving or a working machine, utilizing compressible or non-compressible media as the working fluid. The vane-machine basic embodiment comprises: a cylinder stationary part (A), cylinder rotating parts (B), a rotor (C), covers (D), and vanes with grooves (F). The cylinder stationary part has a shroud (1) within which the rotor with the vanes rotates. In the shroud there are radial rectangular openings (5and6) letting the media in and out. The openings may be of other shapes as well. The inner ring (8) of roller or sliding bearings are rotationally driven by the vanes. The rotor is positioned eccentrically-relative to the shroud axes. At the rotor there are firmly fitted lateral plates (14) that rotate jointly with the rotor. The vane-machine working chamber is delimited with the shroud, the inner rings, the vanes and the plates.
