Abstract

Process for the manufacture of rotors for power steering rotary valves of motor vehicles, characterized in that it comprises, among others, the following steps: block in rotation and in translation the rotor in which several axial grooves regularly distributed in the periphery have previously been roughly defined. Of the rotor; and forming, by punching at the longitudinal edges of at least one groove, notches substantially parallel to the axis of the rotor, the notches each comprising a flat edge substantially parallel to the plane of symmetry of the groove, whose respective distances to the plane of symmetry are perfectly defined.
