The servo control device comprises: - an input member (68) - a servo motor (24) divided by a movable wall (32) into two chambers (28, 30) in communication with a source (48) of fluid under high pressure, and with a source (56) of fluid under low pressure, - an output member (76) moved by the said movable wall (32), - at least one valve (54a, 54b) interposed in one of the said communications. It also comprises an actuating device (62) for displacing the valve (54a, 54b) into one or other of its positions. This actuating device comprises: an input element (64) terminated by a conical pinion (78), a reaction element (72) and, terminating in a second conical pinion (80), a clevis (82) journalled around the two input and reaction elements, and a third conical pinion (86) mounted on the said clevis (82) and in engagement with the first (78) and the second (80) conical pinions, the clevis (82) interacting with the said valve (54a, 54b). <IMAGE> |
