Abstract
A control arrangement for supplying pressure fluid through a supply conduit from a source of pressure fluid to at least two hydraulically operated consumer devices includes, for each of the consumer devices, a valve having a valve member movable axially between a neutral position preventing flow of pressure fluid to the respective consumer device and two working positions respectively connecting the consumer device to the source of pressure fluid or a return conduit. A throttle is located in the supply conduit between a first point of the latter from which a first branch conduit branches off to a first of the valves and a second point from which a second branch conduit branches off to the second of the valves. The arrangement includes further a control valve and a control circuit therefor, controllable at least by the valve member of one of the valves. In the neutral position of all valve members the supply conduit is connected with the return conduit to form therewith a neutral fluid circulation passage.
