Abstract
A hydraulic control arrangement for at least two hydraulic consumers, comprises two pressure compensated multiple position valves, respectively coordinated with the two consumers, and each including a pressure compensating control member which controls a control conduit coordinated with a reversing or unloading valve, which, depending on its position and those of the multiple position valves control flow of pressure fluid from a pump over the multiple position valves to the respective consumer or to a return conduit. This will assure that even during parallel operation of both consumers, the output of the pump will be adjusted to the consumer load in such a manner that energy losses are substantially avoided and control of the two consumers independent from each other is assured.
