Abstract

Device for maintaining at constant value the maneuvering speed of a hydraulic jack capable of being subjected to variable loads and in which the maneuvering speed is a function of the section of the jack's discharge hole, characterized in that it has, to control the passage of liquid through the discharge port of the jack, a distributor in which a movable slide, capable of moving between two positions corresponding respectively to a maximum discharge flow and a minimum discharge flow, is subjected in the direction of increasing flow of discharge, to the action of an antagonistic force of decreasing value, and in the sense of the decrease of the discharge flow, to the action of the pressures created in the cylinder of a shock absorber by the movements of the shock absorber piston attached to the mobile organ sent by the cat.
