Device for locking and pressure adjustment

A device for locking and pressure adjustment, in particular provided for use with a mobile work machine having at least one hydraulic actuator device (12) and a storage device (14), which are fluidly connectable to or separable from one another by means of a first valve device (16), is characterized in that before establishing the fluid connection through the first valve device (16), a controlled pressure equalization between the actuator device (12) and the storage device (14) via an equalization device (24) is initiated in order to prevent an abrupt pressure equalization.
