Patent ID: 6837054

Claim:
An actuator assembly comprising synchronized hydraulic actuators, the assembly comprising: a hydraulic control circuit; a master actuator having a cylinder and a piston defining two chambers inside the cylinder that are connected to the hydraulic circuit; at least one slave actuator having a cylinder and a piston defining two chambers in the cylinder, at least a first one of which is connected to an outlet of a directional control valve, which control valve is connected to the hydraulic circuit and to a control member whose position determines the pressure in the first chamber of the slave actuator; and a mechanical transmission for transmitting a displacement of the piston of the master actuator to the control member of the control valve associated with the slave actuator in such a manner that the displacement of the piston of the slave actuator is servo-controlled to the displacement of the piston of the master actuator by controlling the position of the control member of the control valve associated with the slave actuator.
