    Abstract: A rotary-vane pumping machine has a core structure that includes a stator assembly defining a contoured surface of a stator cavity, a rotor spinning around a rotor shaft axis that is fixed relative to the stator cavity, and end plates disposed on either side of the rotor. The rotor has a plurality of radial vanes slots for housing a corresponding plurality of vanes that slide within the radial vane slot of the rotor. Each of the plurality of vanes has side walls, a tip portion, and a base portion, and the base portion has one or more tabs extending from at least one axial end of the vane. The plurality of vanes, stator cavity, and rotor define a plurality of chamber cells. The core structure is substantially made of low coefficient of thermal expansion Invar materials to achieve precise non-contact sealing clearances between components of the machine.

    Abstract: A slant plate type compressor with a capacity or displacement adjusting mechanism is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the pressure in the crank chamber. The pressure in crank chamber is controlled by control mechanism which comprises a passageway communicating between the crank chamber and a suction chamber, a first valve device to control the closing and opening of the passageway and a second valve device to control pressure in an actuating chamber. The first valve device includes a bellows valve element and a valve shifting element. The valve shifting element of which one end is exposed in the actuating chamber is coupled to the bellows to apply a force to the bellows at another end and thereby shift a control point of the bellows in response changes in the actuating chamber pressure.
