Abstract: A control device includes a valve, having a body connected to the first chamber of a cylinder via a first hydraulic connection and to the second chamber of the cylinder via a second hydraulic connection. The control device includes a first hydraulic duct connected to a first actuating-fluid source, and a second hydraulic duct connected to a second actuating-fluid source. The hydraulic ducts communicate with the body of the valve. The valve further includes a distribution device that is movable within the body of the valve, between a first position, in which the distribution device places the first hydraulic connection and the first hydraulic duct in fluid communication, and a second position, in which the distribution device places the second hydraulic connection and the second hydraulic duct in fluid communication.
