  • Actuating device for at least one fluidically drivable consumer
    Patent number: 12404878
    Abstract: The invention relates to an actuation device for at least one fluidically drivable load (10), such as a hydraulic actuator, consisting of at least one valve controller (V1) for controlling an alternating movement of each load (10) and at least one suspension device (14) which is connected between the valve controller (V1) and each load (10), wherein the suspension device (14) has an additional valve controller (V2), the valve piston (20) of which can be moved in a corresponding valve housing in a continuously adjustable manner. The invention is characterized in that a storage device (16) of the suspension device (14) is connected to the respective load (10) via a fluid path by means of the additional valve controller (V2) in a suspension position (V2.IV) of the valve piston (20) of the additional valve controller (V2). The invention additionally relates to a method for actuating the respective load (10) using such an actuation device.
