Abstract
An apparatus () blocks and adjusts a pressure for a hydraulically controllable actuator (), particularly a lifting unit () of a machine (). The apparatus () allows a working chamber () to be selectively connected to a pressure supply unit () having a storage device () or to a discharge end (), in particular a reservoir end, by a valve unit (). In a controlling position of the valve unit (), when the storage pressure in the storage device () is greater than the working pressure in the working chamber () of the actuator (), the storage pressure is relieved in the direction of the discharge end () until the working pressure has been reached.
