1. An actuating device for at least one fluidically drivable consumer, comprising at least one valve device for controlling an alternating movement of a respective consumer and at least one suspension device which is connected between the at least one valve device and the respective consumer, wherein the suspension device has a further valve device, the valve piston of which can be moved in an associated valve housing in a continuously adjustable manner; wherein,
in a suspension position of the valve piston of the further valve device, an accumulator device of the suspension device is connected to the respective consumer via a fluid path by means of the further valve device;
the valve piston of the further valve device can be disposed in a charging position in which, for charging it, the accumulator device is connected to the pressure supply port by the further valve device via a further fluid path;
the valve piston of the further valve device can be disposed in at least one disconnecting position in which said valve piston disconnects all ports of the further valve device from one another; and wherein
a disconnecting position between the suspension position and the charging position is provided.
