ABSTRACT:
A vane control unit for a vane pump having reversible control, the pump having a rotor, a rotor shaft and a vane control unit including vane thrusters inserted into housings arranged in the rotor shaft and designed to control the movement of the vanes outside of their respective housings in the rotor. The vane control unit has thrusters, each of the thrusters is adapted to be connected to two diametrically opposed vanes. The thrusters are semi-cylindrical in shape, have a planar surface and are arranged in groups of two so that their axes, each in their planar surface, are concurrent and coplanar. The thrusters are mounted in sliding engagement in respective cylindrical channels perpendicular to the rotational axis of the rotor shaft and form an angular space between them which depends on the number of vanes in the pump.
