Abstract (en)
[origin: WO2004051092A1] The invention relates to a hydraulic dual circuit system for controlling consumers (8, 10) of a mobile device, especially a chain-operated device. The two circuits can be combined by means of a combination valve system (12) for selected consumers. The consumers are supplied with pressure medium via a load-independent flow division (LIFD) orifice gauge (14) and an LIFD pressure scale (16). The combination valve system (12) is configured in such a manner that the combined volume flow from the combined circuit downstream of the orifice gauge (14) is supplied to the other circuit and/or that combination is carried out relatively late, i.e. in a phase-delayed manner to the combined consumer.
