Abstract:
1. A circuit arrangement, comprising: first and second individual series consumers arrange in series with one another and forming a series section; at least one individual parallel consumer connected in parallel relative to said series consumers in a hydraulic supply circuit; at least one supply pump within said hydraulic supply circuit; a fluid return line within said hydraulic supply circuit; a load sensor connected to said consumers and determining a highest load pressure for said series and parallel sections at a time; a conduit conveying the highest load pressure at the time as a control pressure to a valve unit, said valve unit being operable to dramatically choke said fluid return line coupled thereto if load pressure in said parallel section is higher than load pressure in said series section until said supply pump raises pressure at least to pressure required in said parallel section; and first and second bypass manometric balances are connected in fluid communication to said first and second series consumers, respectively.
