发明名称 Controllable vane pump
摘要 A control ring in sliding contact with the radially outer ends of fluid displacing vanes on a pump rotor, is angularly adjustable about a pivot formation in a pump housing on one radial side of the rotor opposite a limited sealing surface on the housing having a center of curvature on the rotor axis. A sealing element pivotally mounted on the control ring is biased into wiping contact with the sealing surface to divide the pump housing into inlet and outlet pressure chambers.
