ABSTRACT:
A rotary vane pumping machine have a core structure and peripheral components interfacing with the core structure. The core structure 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. 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.
