Abstract

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.
