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.

Claim (Index 12):
A fuel supply device for supplying fuel to an internal combustion engine, in particular of a motor vehicle, having a first injection device for effecting a direct injection of fuel, having a second injection device which is provided in addition to the first injection device and which serves for effecting an induction pipe injection of fuel, having a high-pressure fuel pump for supplying the fuel to the first injection device, and having a low-pressure fuel pump for conveying the fuel to the high-pressure fuel pump, which high-pressure fuel pump comprises at least one first low-pressure port, via which the fuel can be fed to the high-pressure fuel pump from the low-pressure fuel pump, 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, 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 the second injection device, a pump housing, in which there is arranged at least one conveying element which is movable relative to the pump housing and which serves for conveying the fuel to the first injection device, a compression chamber, the volume of which is variable by movement of the conveying element, and a collecting chamber, which is arranged on a side of the conveying element averted from the compression chamber and which is variable in terms of its volume by movement of the conveying element and which serves for collecting fuel from the compression chamber, wherein the collecting chamber is fluidically connected to the low-pressure chamber,\n characterized in that at least a part of the fuel flowing through the first low-pressure port flows from the first low-pressure port to the second low-pressure port, circumventing the collecting chamber, and flows through said second low-pressure port.
