Abstract
The invention relates to a valve block () for a control device comprising a valve () whose valve piston () is subjected to the action of a control pressure when in its open position and to the action of a return spring () when in its closed position. The closing force of the return spring () can be decreased or increased by an actuator, which can be displaced toward a position that increases the closing force and one that decreases the closing force. In order to simplify the displacement or adjustment and to improve reliability, the displacing movement of the actuator () in the direction of movement that increases the closing force of the return spring () is limited by a stop element () in a position in which the closing force of the return spring () reaches its limited maximum value.
