Circular rotor 1 rotates about fixed axis A, eccentrically located with respect to the geometric axis of housing 3. Vanes 2 turn about axes B. When the rotor rotates, vanes 2 are held against the housing by centrifugal force and deliver liquid in the direction of the arrows. Vanes 2 are retracted into slots a in rotor 1.
