Abstract: The invention relates to a fluid distributor for a heavy-construction machine, comprising a body and a pressure-reducing means which is mounted in said body and comprises a pushrod arranged in a cavity of the body, a plunger being mounted in an oscillating manner. At least one guide in which the pushrod is displaced is immobilized in the cavity, a first seal and a second seal respectively ensuring the hydraulic sealing inside and outside the guide. Said guide comprises at least part of the upper guide and part of the lower guide which are nested inside each other and mutually define a recess facing the pushrod, the first seal being trapped in the recess.

Abstract: The invention concerns a fluid distributor, in particular a hydraulic manipulator comprising a body (5), a pressure reducing valve (2) mounted in the body comprising a plunger (3) mobile in translation and whereof the displacement is controlled by a push-rod (11), a control member (6) including at least one finger (10) for modifying the position of the push-rod, means forming a solenoid (15) mounted in the body, a frame (16) adapted to be driven in translation simultaneously with the push-rod. The dispenser further comprises means for catching (20) the frame on the finger delimiting a window wherein the finger projects substantially transversely, the push-rod being mounted so as to pass right through the frame and project into the window, and the finger being interposed between the catching means and the push-rod.
