Abstract
Disclosed is a hydraulic system for supplying primary and auxiliary pressure medium consumers with different system pressures, which exceed the load pressure by a pre-determined control pressure differential. Primary load pressure is used to produce a first control pressure differential for operating a primary pressure medium consumer. Auxiliary load pressure is converted in an amplifying device to produce a second, higher control pressure differential for operating an auxiliary pressure medium consumer. The amplifying device consists of a pressure reducing valve, which is permanently adjusted to a pre-determined reduced pressure and has a line conducting the system pressure connected to a first pressure inlet, a load reporting line conducting the load pressure of the auxiliary pressure medium consumer connected to a second inlet and a load reporting line subjecting the pressure control valve to increased load pressure connected to an outlet and the control piston is subjected on its one side to the force of a permanently adjusted spring.
