Patent ID: 8281583

Claim:
A hydraulic control assembly for controlling hydraulic consumers of a mobile machine, having a load reporting line ( 26 ) that can be subjected to the highest load pressure of a plurality of hydraulic consumers, triggered simultaneously each via a respective main control valve ( 38 , 57 ), and that is connectable by an end portion ( 26 a ) to a pump regulator ( 25 ), and having a pressure limiting valve ( 50 ), with which the control pressure in the end portion ( 26 a ) of the load reporting line ( 26 ) is limitable, wherein the pressure limiting valve ( 50 ) is adjustable as a function of the magnitude of a pilot control signal serving to trigger a main control valve ( 38 , 57 ), wherein the pressure limiting valve ( 50 ) is hydraulically adjustable and has an adjusting piston ( 73 ) bordering on a pressure chamber ( 74 ) that communicates with a control line ( 86 ), and wherein the pilot control signal is a pilot control pressure, which is generated by an adjustable pilot control valve ( 79 ) from a supply pressure and prevails in a pilot control line ( 82 ) of a main control valve ( 38 , 57 ); and that as a function of the switching position of an arbitrarily actuatable multi-way valve ( 87 ), the pressure chamber ( 74 ) of the pressure limiting valve ( 50 ) is capable of being subjected to the pilot control pressure or to the supply pressure.
