Abstract

A hydraulic control arrangement, which serves to supply pressure medium to at least two hydraulic consumers via a common pump 4, is provided. The pump 4 has an integral pump regulator. The control arrangement has at least two variable metering orifices 8a, 8b; 108a, 108b of which a first is disposed between a feed line 6; 106, which goes out from the pump 4, and the first consumer, and a second is disposed between the feed line 6; 106 and the second consumer. Furthermore, at least two pressure balances 12a, 12b; 112a, 112b are provided, of which the first is connected in series after the first metering orifice 8a; 108a and the second is connected in series after the second metering orifice 8b; 108b. A respective regulating piston of the pressure balances 12a, 12b; 112a, 112b can be acted upon, on a front side, by the pressure after the respective metering orifice 8a, 8b; 108a, 108b, in the opening direction, and by a highest load pressure of the consumers that is present in a rear control chamber, or by a pressure that is derived therefrom, in the closing direction, according to the principle of load-independent flow distribution (LIFD), via a common load indicating line 14, 18; 114, 118. The common load indicating line 14, 18; 114, 118 can be acted upon by pump pressure - instead of being acted upon by the highest load pressure of the consumers - via a safety valve 2; 102; 202, or emergency stop valve.
