Abstract
A hydraulic valve includes a valve body and slide, along with control pieces consisting of two thrust bearings rigidly mounted with a link which is mounted through an axial hole of the slide valve and through the axial holes of the two respective secondary pistons. The slide valve and the secondary pistons are mounted so as to provide an ample gap between the thrust bearings. The secondary pistons, located on either side of the slide valve, delineate two rear chambers which are fed with low pressure fluid. Thus, a gradual displacement of the slide valve is permitted.
