Abstract (en)
[origin: EP0466581A1] The invention relates to the sector of vane pumps. <??>The vane control assembly according to the invention, of the type comprising vane pushers inserted into the shaft of the rotor and intended for controlling the withdrawal movement of the vanes from their receptacle in the rotor, each pusher being connected to two diametrically opposed vanes, is characterised in that the pushers (2, 3) are of semi-cylindrical shape and are arranged in groups of two, in such a way that their axes (A-A, B-B), each contained in their plane face (6, 7), converge, so as to slide in respective cylindrical channels (4, 5) perpendicular to the axis of rotation of the shaft (1) and forming an angular deviation relative to one another. <??>The invention is used for the production of reversible vane pumps. <IMAGE>
