<p>A mechanical feedback control device (38) for a redundant hydraulic actuator (1) having two hydraulic cylinders (2, 3) operated by respective hydraulic valves (20, 21) and interposed between a fixed connection (9) and a movable connection (11) of the actuator (1); the device (38) having an input lever (40) connected to two feedback rods (43) connected to the movable connection (11) of the actuator, and a transmission lever (44) which, when moved by the input lever (40), rotates a pin (55) to activate two shafts (64, 65) controlling respective slides (34, 35) of the valves. The input lever, the transmission lever (44) and the pin (55) form a closed-loop structure for transmitting displacement to each of the shafts (64, 65), so that each of the slides (34, 35) can be moved via two different kinematic chains. <IMAGE> <IMAGE></p> |
