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

Various embodiments may include a high-pressure fuel pump with: a pump housing including a pressure chamber and a pump piston movable up and down within the pressure chamber along a movement axis; and a low-pressure damper including a damper volume arranged on the pump housing and damper elements distributed symmetrically around a damper longitudinal axis. The damper longitudinal axis is arranged at an angle of between 5&#xb0; and 175&#xb0; in relation to the movement axis.
