The invention relates to a supply system (1) for a hydraulically actuated consumer (15,17) of a working device which is added to or coupled to tractor. According to the invention, a center valve (8) prefining a pressure-medium volume flow is arranged on the tractor, wherein an advance line and a return line (18,20) are connected to the center valve on the working-device side. Several consumers (15,17) are mounted in parallel in said advance line and return line. One respective consumer (15,17) is hydraulically connected to the center valve (8) by means of a distributor valve arrangement (26,27,28,29). According to the invention, the pressure-medium volume flow is adjusted on the tractor side. The pressure medium is distributed on the working device side by means of the distributor valve arrangement (26,27,28,29). |
