Abstract (en)
[origin: EP1548287A1] The device has a hydraulic circuit with a pump (3) for supplying, from a hydraulic tank (5), two chambers (2a, 2b) of a hydraulic actuator (2) through a servo-valve (4). Pipelines (8a, 8b) of the valve are connected to the respective chambers of the actuator through anti-return valves (9a, 9b). The pipelines are connected to the hydraulic tank by calibrated metering jets (10, 10b), in upstream of the anti-return valves.
