Abstract:
1. A hydraulic dual-circuit system for activating consumers of a mobile device, in particular a crawler-track device, in the case of which a variable-displacement pump is assigned to each hydraulic circuit ( 2 , 4 ), via which the assigned consumers may be supplied with pressure medium, it being possible to connect the two circuits ( 2 , 4 ) via an interconnecting valve system ( 38 ) in a manner such that the variable-displacement pump of one circuit ( 2 , 4 ) pumps pressure medium into the other circuit ( 4 , 2 ), and it being possible to activate the variable-displacement pumps as a function of the load pressure in the assigned circuit ( 2 , 4 ), wherein the interconnecting valve system (
