    摘要： A scroll compressor may include a scroll pumping mechanism which includes an orbiting scroll having an orbiting scroll wall extending axially from an orbiting scroll plate towards a fixed scroll and a fixed scroll having a fixed scroll wall extending axially from a fixed scroll plate towards the orbiting scroll. An axial end portion of one of the scroll walls includes a first sealing arrangement and a second sealing arrangement arranged in series along the scroll wall from the inlet to the outlet for sealing between the axial end portion of the scroll wall and the scroll plate of the opposing scroll. The first sealing arrangement may have first sealing characteristics which are selected according to the sealing requirements local to the first sealing arrangement and the second sealing arrangement may have second, different sealing characteristics which are selected according to sealing requirements local to the second sealing arrangement.

    摘要： The invention relates to a vane for a rotary pump, comprising a pump housing and rotor, mounted to rotate therein, whereby the vane is mounted to be displaceable in the rotor, touches an inner circumferential surface of the pump housing and defines a vacuum chamber and a pressure chamber. The vane has a constant length, the inner circumferential surface is made from metal and the vane has vane tips, the hardness of which is greater than the hardness of the inner circumferential surface.

    摘要： The invention concerns a rotary volumetric machine comprising a stator (9) wherein a cylindrical chamber (2) is provided, a rotor housed in the cylindrical chamber (2) integral with a shaft (15), vanes (3, 7) formed on the rotor, and abutting elements (5, 6, 25) capable of being displaced by actuating means between: an extended position into the volume of the cylindrical chamber (2) in operational phase so as to generate volume variations between the vanes (3, 7) and the abutting elements (5, 6); a retracted position into the stator (9) to allow through the vanes (3, 7) from one side of the abutting elements (5, 6, 25) to the other. The invention is characterized in that: the rotor comprises a disc (1), two concentric flanges (4, 8) arranged on either side of said disc (1) and two fixed vanes (3, 7) arranged diametrically opposite on either side of said disc (1) each one against one surface of said disc (1) and assembled at the periphery of a flange (4, 8) so as to obtain an assembly with rotational equilibrium; in extended position into the volume of the cylindrical chamber (2), the abutting elements (5, 6, 25) are positioned proximate to, but non in contact with, the flanges (4, 8).

    摘要： A vane pump (10) includes a cylindrical rotor (78) rotatable inside of an oval-shaped rotor chamber (66) of cam ring (46) disposed between a pressed plate (42) and a pressure plate (44). The rotor has opposite sides (82a, 82b) and a peripheral outer surface (80) in which radial vane slots (86) are formed and guide slideable vanes (88). The rotor (78) is coated on its surfaces with a film (150) of abradable coating material which reduces the operating clearance between the rotor (78) and the thrust and pressure plates (42, 44) and cam ring (46) so as to increase the volumetric efficiency of the pump (10).
