Abstract

A high-pressure fuel pump includes a pump housing with a housing wall and a damping device configured to damp inlet-side pressure pulses by varying a damping volume with an elastically deformable wall. At least one section of the elastically deformable wall is formed from one or more of at least one part of a jacket-like area of the housing wall and at least one part of a sealing support. The section is embodied such that it includes at least one main part configured to vary the damping volume.
