Abstract (en)
[origin: WO2011067008A1] In a fuel injection device (10) for an internal combustion engine comprising a fuel pre-supply pump (13), which delivers fuel from a fuel tank (11) via a delivery line (18) on the pressure side to a high pressure fuel pump (12), the pre-supply pump (13) comprises a drive (13a) that is independent of the high pressure pump (12), in particular an electric drive. According to the invention, the delivery line (18) on the pressure side is connected via an electrically actuated quantity difference valve (21) having an adjustable valve cross-section to a return line (17).
