Abstract
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.
