Description

RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 736,959 filed Nov. 15, 2005, which is hereby incorporated herein by reference.FIELD OF THE INVENTION

[0002] The present invention relates to rotary vane machines and, more particularly, to a rotary vane machine wherein the vane is driven rather than the rotor.BACKGROUND OF THE INVENTION

[0003] Rotary vane machines are distinguished from virtually all other fluid displacement machines in their remarkable simplicity. The operating efficiency of such machines, however, is negatively impacted by machine friction. Friction in non-guided rotary vane machines can arise from the rubbing of the tip of the sliding vane against the inner contour of the stator wall. Governing the motion of the vane by the stator wall contour also can inhibit the area through which fluid can enter or exit the machine. This can result in increased fluid flow pressure losses in the inlet and outlet port regions.
