ABSTRACT:
A hydraulic arrangement with a pressure medium source and at least two consumers connected to it is provided in which the sum of the streams consumed by the consumers can be greater than the maximum delivery stream of the pressure medium source, where one of the consumers is preferred and receives the full stream required by means of a special device and a second consumer is connected to a multiway valve that is controlled by control pressure, whereby, in order to arrive at a small cost-favorable multiway valve, the multiway valve in the device that causes the preference of the consumer is located between a low-pressure medium source and the control pressure chamber of an additional multiway valve that is hydraulically controlled against spring force and is installed in front of the second consumer, and that the spring-side control pressure chamber of this multiway valve is acted upon by the pressure in the control pressure line and the opposite control pressure chamber of this multiway valve is acted upon with the pressure of the stream flowing to the privileged consumer.
