Abstract: The invention relates to a high-pressure fuel pump (10) having a housing (12) in which a pressure-limiting valve (38) is arranged in a bore (36), wherein the bore (36) leads into an inflow volume (30) of a low-pressure inflow (22).

Abstract: The present disclosure relates to fuel delivery systems for a motor vehicle. Some embodiments include a housing with a wall and a connector opening, a high-pressure connector including a wall circumferentially bordering a recess extending along a longitudinal central axis of the high-pressure connector, a radial indentation formed at the inner side in the wall in the housing connector region adjacent to the transition region, and an axial indentation formed at the outer side in the wall in the transition region adjacent to the intermediate region. The high-pressure connector may have a housing connector region, an intermediate region, and a transition region. An outer diameter of the high-pressure connector is larger in the housing connector region than in the intermediate region and the inner diameter is larger in the housing connector region than in the intermediate region. The wall of the housing delimits a recess around the connector opening.

Abstract: The invention relates to a high pressure fuel pump (10) comprising a housing (12) and a flange (14) by means of which the housing (12) can be fastened to an engine block or cylinder head, the flange (14) being formed of at least two flange parts (26) that are separate from the housing (12) and are separated from each other, and that overlap mutually in the fastened state of the housing (12).
