Abstract (en)

[origin: EP0636796A1] The invention relates to a hydraulic amplifier, particularly for directional valves, having a movable jet-deflecting device (6, 8) which changes the direction of a central jet directed towards two receiver ports (5). According to the invention, a return nozzle (10) with a return port (9) is arranged in such a way that it forms a variable choke point for the returning hydraulic fluid as a function of the position of the jet-deflecting device (6, 8). <IMAGE>
