The invention relates to a high-pressure fuel pump () having a housing () in which a pressure-limiting valve () is arranged in a bore (), wherein the bore () leads into an inflow volume () of a low-pressure inflow ().

High-pressure fuel pump

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 disclosure relates to a fuel injection system having a valve arrangement for connecting a pressure chamber of a high-pressure fuel pump to a high-pressure accumulator. The valve arrangement has an outlet valve and a pressure-limiting valve. An outlet valve seat and a pressure-limiting valve seat are formed on a common valve seat element which is formed in one piece, and are arranged eccentrically with respect to one another.

Fuel injection system for an internal combustion engine

Various embodiments include a high-pressure fuel pump for a fuel injection system comprising: a housing defining a housing bore with a pressure chamber in a first end region and a leakage chamber in a second end region; a pump piston, during operation of the high-pressure fuel pump moved in translation between the pressure chamber and the leakage chamber along an axis; wherein the leakage chamber includes a leakage collecting region and an equalizing region arranged in circular annular fashion around the pump piston guiding section and extending parallel to the axis from the leakage collecting region toward the pressure chamber; and a low-pressure damper arranged in the equalizing region, the low-pressure damper comprising an annular piston damper and an annular piston guided to move along the axis within an annular bushing.
