ABSTRACT:
The two stator members of the distributor (5, 6), between which the rotor of the distributor (10) is placed, are assembled under an axial prestress by an assembly tie rod (12) comprising, at one end, an annular shoulder (17) cooperating in bearing against a bearing surface of the adjacent stator member (5) and, at its other end a profiled annular groove (18) in which a metal ring (23) is fitted by force, under axial stress with radial deformation, so as to exert an axial stress on a radial bearing surface of the adjacent stator member (6). Application to the construction of rotary hydraulic distributors, especially for power-assisted vehicle steering systems.
