Abstract
A vane-type pump having a rotatable shaft, a cylindrical housing, a rotor secured to the shaft so as to be rotated within the housing with the center line being offset from that of the housing, and a number of vanes radially shiftably received within the radial slots formed in the rotor is disclosed wherein a cylindrical casing is disposed between the cylindrical inner periphery of the housing and the rotor, the cylindrical inner periphery of the casing being adapted to have the radially outward peripheries of the vanes abut against it due to centrifugal force applied thereto when they are rotated together with the rotor, and the casing is constituted to be rotated by the shaft through any suitable transmission mechanism arranged between them in the same direction as the rotational direction of the rotor, but at a velocity lower than that of the shaft.
