A hydraulic supply system for feeding pressurized fluid to a hydraulic consumer (12) having at least one consumption zone (14, 16) comprises a pressurized fluid source (18) feeding pressurized fluid from a reservoir (26) into a main pressure conduit (24), a main control valve (34, 36) that is associated with each of a hydraulic consumer's consumption zones (14, 16) to which pressurized fluid is to be fed and that is to be adjusted using a control fluid pressure in order to establish and interrupt the connection between the main pressure conduit (24) and a consumption zone (14, 16), and a pilot valve (38, 40) for applying the control fluid pressure to the main control valve (34, 36). The pilot valve is fed at an inlet pressure lying below the fluid pressure in the main pressure conduit (24) by means of a pressure reducer (42).
