Abstract

This invention relates to an assembly of a hydraulic motor and a combined device for immobilization, comprising: a reaction cam; a cylinder-block mounted to rotate with respect to the reaction cam; a first immobilization member fast with the cylinder-block; a second immobilization member fast with the reaction cam and capable of being disposed in a first position, in which the first and second immobilization means are fast with one another, and a second position, in which these first and second immobilization members do not cooperate for their mutual immobilization. The device for adjusting the relative position of the first and second immobilization members comprising a jack comprising a chamber. According to the invention, a) one of the immobilization members is coupled to an immobilization device, mounted to move in translation on the element of the motor with which this immobilization member is fast; b) the immobilization device constitutes, with one of the elements defining the chamber of the jack, a monobloc assembly; c) one of the immobilization members comprises an immobilization catch capable of cooperating with a housing formed in the other immobilization member; and d) the first and second immobilization members are contained in the chamber. One application is the production of an axially compact, simple immobilization device.
