Abstract: A valve arrangement arranged in a flow connection between a storage chamber and an operating chamber is actuated by means of an electromagnetic actuating device and, depending on an input rotational movement to a closure element, controls a fluid flow from the storage chamber into the operating chamber. Rotational movement is provided by a rotary armature arranged immediately next to an electromagnet and fixed to a common shaft with the closure element. The magnetic flux path of the electromagnetic actuating device is shortened and thus the efficiency of the arrangement is increased significantly.
