Abstract (en)
[origin: WO2011098305A1] The invention relates to a method for supplying a high-pressure pump (1) in a fuel injection system of an internal combustion engine with fuel, wherein for delivery and for controlling the delivered quantity a delivery pump (3) is used, wherein said delivery pump is arranged in a low-pressure circuit (2) and operated by an electric motor and by means of which, depending on the respective selected engine speed, a certain quantity of fuel is fed to the high-pressure pump (1), in which the fuel is first compressed and then fed to a fuel high-pressure accumulator (4). According to the invention, the fuel pressure on the intake side of the high-pressure pump (1) is controlled by means of a pressure control valve (5), wherein a supply of the high-pressure pump (1) with fuel for lubrication and/or cooling via the low-pressure circuit (2) and the delivery pump (3) is assured when the pressure control valve (5) is in the closed position. The invention further relates to a fuel injection system.
