Disclosed is a circuit for actuating one or more hydraulic consumer(s). The hydraulic consumer(s) are actuated at their terminals with proportionally adjustable directional valves which can be actuated separately for any direction of movement. The directional valves and a hydraulic pump, which provides a system pressure, are actuated electronically. In dependence on the desired speed and direction of movement, an open- or closed-loop electronics unit actuates the directional valves and the hydraulic pump. It is thus possible, if the pressure and load conditions are known, to determine purely by computation the required valve openings which are necessary for the desired movement. |
