  • Patent number: 7401465
    Abstract: A hydraulic system is provided for an engine driven vehicle. The hydraulic system includes a higher pressure engine driven pump for supplying pressurized fluid to a higher pressure circuit via a first supply line. The system also includes a lower pressure engine driven pump for supplying lower pressure fluid to a lower pressure circuit via a second supply line. The system also includes a pressure responsive relief valve. The relief valve has a sensing port connected to the first supply line, an inlet connected to the first supply line, and an outlet connected to the second circuit via the second supply line. The relief valve opens when a demand of the higher pressure circuit is satisfied. A cut-off valve controls communication between the high pressure circuit and a reservoir, and a control unit controls the cut-off valve as a function of operation of the high pressure circuit.
