The invention relates to a hydraulically controlled device comprising a double-acting cylinder (VR1) applying a force in one direction to an external element in one operational phase, and receiving a force in an opposite direction in another operational phase, a hydraulic pump (P), a flywheel coupled with the pump (P), a hydraulic accumulator (ACC), and a vessel (R), the cylinder (VR1) comprising a piston defining an actuation chamber (CA1) and a return chamber (CR1), a connector between the actuation chamber and the pump (P), a connector between the actuation chamber and the accumulator (ACC), a connector between the pump (P) and the vessel (R), a connector between the pump (P) and the accumulator (ACC), and a connector between the return chamber and the vessel (R), said pump (P) and the connectors being controlled such that during one operational phase, the pump (P) supplies the actuation chamber (CA1) such as to apply a force to the external element and the accumulator (ACC) assists the pump (P), and during another operational phase when the cylinder receives a force from the outside, the actuation chamber (CA1) fills the accumulator (ACC) and the return chamber is supplied by the vessel (R).
