A method and a pressurized medium system, including: at least one actuator to generate sum forces effective on a load; a working chamber operating by displacement and located in the actuator; a charging circuit of a higher pressure, which is a source of hydraulic power; a charging circuit of a lower pressure, which is a source of hydraulic power; a control circuit, that couples the charging circuit of higher pressure and the charging circuit of lower pressure, in turn, to the working chamber; wherein the working chamber is capable of generating force components that correspond to the pressure of the charging circuit to be coupled to the working chamber, and each force component produces at least one of the sum forces either alone or in combination with the force components produced by the other working chambers of the actuator.
