Spring force is adjusted by an adjusting member (16a), with member movement in direction of spring force increase defined by a stop element (112) in a position, in which the closing force of the spring reaches its max. value. Adjusting member and stop element are contained in module (82) screwed to the valve block. The valve is a pressure reduction valve, or flow control valve, and is located in an adjusting pressure line (24) to a cylinder for displacement volume control.
