Embodiments relate to a high-pressure fuel pump having a pump piston which, during operation, moves in translation between a pressure chamber and a leakage chamber. The leakage chamber has a leakage collecting region and an equalizing region. A low-pressure damper having a bellows-shaped corrugated damper plate is arranged in the equalizing region.

High-pressure fuel pump for a fuel injection system

The invention relates to a high-pressure fuel pump for supplying fuel to a first injection device of an internal combustion engine, in particular of a motor vehicle, having at least one first low-pressure port, via which the fuel can be fed to the high-pressure fuel pump from a low-pressure fuel pump for conveying the fuel, having at least one low-pressure chamber, to which at least a part of the fuel fed to the high-pressure fuel pump via the first low-pressure port can be fed, having at least one second low-pressure port, for conducting the fuel conveyed by means of the low-pressure fuel pump and fed to the high-pressure fuel pump away from the high-pressure fuel pump to a second injection device provided in addition to the first injection device.

High-pressure fuel pump and fuel supply device for an internal combustion engine, in particular of a motor vehicle

The disclosure relates to a control method for controlling at least one injector valve in a fuel injection system of an internal combustion engine. An opening time of the injector valve is selected such that, in a fault situation in the fuel injection system, an opening time of the injector valve is situated in a pressure valley of a pressure oscillation prevailing in a high-pressure region of the fuel injection system.

Control method for controlling an injector valve in a fuel injection system, and fuel injection system

Embodiments relate to a valve arrangement for a fuel injection system, including a valve disc that has a valve opening. A deformable valve sheet that is movable in a movement direction is provided to open and close the valve opening, and a valve shaft of a movement-activation arrangement, provided to activate the movement of the valve sheet, is secured to the valve sheet. The embodiments also relate to a high-pressure pump which includes the valve arrangement.
