Patent ID: 8006490

Claim:
A hydraulic control device with a load-sensing design for actuating a first hydraulic consumer ( 15 ) and a second hydraulic consumer ( 30 ), with which a first control valve ( 18 , 20 ) for actuating the first hydraulic consumer ( 15 ) and a second control valve ( 32 ) for actuating the second hydraulic consumer ( 30 ) are provided, a first load signal may be measured on the basis of a load pressure with which the first hydraulic consumer ( 15 ) is acted upon, and a second load signal may be measured on the basis of a load pressure with which the second hydraulic consumer ( 30 ) is acted upon; pressure medium from a pressure medium source ( 10 ) may be supplied in parallel to the first control valve ( 18 , 20 ) and to the second control valve ( 32 ), a load signal path ( 24 ) is provided, which may be acted upon with a highest currently measured load signal in order to actuate an actuating component ( 11 ) assigned to the pressure medium source ( 10 ), and with which a limiting device ( 35 ; 48 ) is provided, which allows the second load signal to be limited to a predefined signal limit value, wherein switching means ( 36 ; 44 ) are provided that may be actuated by means of the second load signal such that, at the latest when the second load signal reaches the signal limit value, the signal conveyed on the load signal path ( 24 ) is limited by the limiting device ( 35 ; 48 ).
