<p>The arrangement has a piston (52) controlling several metering orifices (40,42,44,46), an adjustable pressure divider with two throttles, and a centering spring unit (54) for the piston. The flow cross section of at least one of the throttles can be changed. The throttle (20) is a continuously or step-by-step adjustable pre-control valve. The fixed throttle (64) is located in a control oil flow path between a first connection and the first throttle valve. The metering orifice piston is guided in a sleeve (38), with windows (40,42,44,46), which form the orifices and are each associated with one of the working connections (A,B,C,D), and are regulated by the piston.</p> |
