Abstract

Procédé de fabrication de rotor pour distributeur hydraulique. Il consiste à immobiliser le rotor, à la périphérie duquel ont été préalablement définies de façon grossière plusieurs rainures axiales, à former au moyen d'un premier outil des entailles parallèles à l'axe dans les bords des rainures, et à former ensuite un chanfrein de part et d'autre de la rainure entaillée. Application notamment à la fabrication des valves rotatives pour servodirections de véhicules.Process for manufacturing a rotor for a hydraulic distributor. It consists in immobilizing the rotor, at the periphery of which several axial grooves have been previously defined in a rough manner, in forming, by means of a first tool, notches parallel to the axis in the edges of the grooves, and then forming a chamfer. on either side of the notched groove. Application in particular to the manufacture of rotary valves for vehicle power steering.
