ABSTRACT:
A positive displacement fluid handling apparatus comprises a hollow circular cylindrical vane guide with a plurality of slotted axial openings included in the cylindrical wall thereof and a plurality of vanes, wherein the hollow circular cylindrical vane guide is disposed rotatably within a circular cylindrical cavity included in the body of the apparatus in an eccentric and tangential relationship to the cylindrical wall of the cylindrical cavity and the plurality of vanes are disposed rotatably about the central axis of the circular cylindrical cavity and respectively engage and extend through the plurality of slotted axial openings included in the hollow circular cylindrical vane guide in such a way that the radial edges of the vanes slide on the circular cylindrical wall of the cylindrical cavity and, consequently, the motion of fluid moving from the inlet to the outlet of the apparatus through a crescent-shaped flow passage between the cylindrical wall of the cylindrical cavity and the hollow circular cylindrical vane guide is correlated to the rotating motion of the vanes and vice versa.
