<p>A method and a pressurized medium system, comprising: at least one actuator (23) or actuator unit, by means of which it is possible to generate sum forces (Fcyl) effective on said load; at least one working chamber (19, 20, 21, 22) operating by the principle of displacement and located in said actuator or actuator units; at least one charging circuit (HPi, HPia) of a higher pressure, which is a source of hydraulic power; at least one charging circuit (LPi, LPia) of a lower pressure, which is a source of hydraulic power; a control circuit (40), by means of which at least one said charging circuits of higher pressure (HPi, HPia) and at least one of said charging circuits of lower pressure (LPi, LPia) can be coupled, in turn, to at least one of said working chambers (19, 20, 21, 22); wherein each of said working chambers (10, 20, 21, 22) is capable of generating force components (FA, FB, FC, FD) that correspond to the pressures of the charging circuits (HPi, HPia, LPi, LPia) to be coupled to said working chamber, and each force component produces at least one of said sum forces either alone or in combination with the force components produced by the other working chambers of said actuator or actuator unit. The actuator unit is, for example, a slewing device or a rotating device. The system utilizes a controller in the control of the control circuit.</p> |
