Abstract (en)
[origin: EP2189666A1] A hydraulic device for controlling an actuator (2), comprises a body (8) having a first conduit (9; 109) destined to be connected to a first chamber (3) of the actuator (2), the body (8) having a second conduit (10; 110) destined to be connected to a second chamber (4) of the actuator (2), a control valve (15) being arranged along the first conduit (9; 109) in order to enable an operating fluid to be selectively discharged from the first chamber (3), the control valve (15) comprising an obturator element (16); the hydraulic device further comprises a pilot valve (20) for sending a pilot fluid to the control valve (15) such as to move the obturator element (16) in a controlled way, a component (34) having a hydraulic resistance being arranged along the first conduit (9; 109), the body (8) having a connecting conduit (32) connecting the first conduit (9; 109) and the second conduit (10; 110) in order to send the operating fluid coming from the first chamber (3) towards the second chamber (4).
