Abstract (en)
[origin: WO2009129942A1] A hydraulic dual-circuit system for actuating consumers (12, 14) and a method for actuating consumers of a hydraulic dual-circuit system are disclosed, wherein the two circuits (1, 2) can be connected to one another via an interconnecting valve arrangement (4), with the result that the variable displacement pump (8, 10) of one circuit (1, 2) adds pressure medium into the other circuit (2, 1). The dual-circuit system has a deactivation device (ß), via which the adding is deactivated if the pressure-medium requirement in the connected circuit is smaller than the maximum pump delivery flow and greater than a switchover pressure-medium requirement. The latter can lie, for example, at approximately 80% of the maximum pump delivery flow.
