  • Patent number: 10851749
    Abstract: The invention relates to a high-pressure pump (1), in particular for a motor vehicle, for conveying a fluid, in particular fuel, e.g. diesel fuel, comprising a drive shaft having at least one cam, at least one piston, at least one cylinder (6) for mounting the at least one cam, wherein the at least one piston is supported on the drive shaft by the at least one cam, so that a translational motion can be carried out by the at least one cam as a result of a rotary motion of the drive shaft, at least one cover cap (8), which is attached indirectly or directly to the outside of the cylinder (6), wherein one end (18) of the at least one cover cap (8) rests on a projection (16) of the remaining high-pressure pump (1) for the interlocking attachment of the end (18) of the cover cap (8) to the projection (16).

  • Patent number: 10309359
    Abstract: The invention relates to a high-pressure fuel pump (1), in particular of a common rail injection system of an internal combustion engine, having a pump cylinder head (3), having an intake valve (6) arranged in the pump cylinder head (3) in the direction of a pump cylinder axis, and a high-pressure fuel outlet (5) arranged laterally on the pump cylinder head (3), wherein a protective cap (10, 10a) at least partly covering the high-pressure fuel pump (1) is provided. According to the invention, a high-pressure fuel pump (1) having a protective cap (10, 10a) is provided, in which the protective cap (10, 10a) can be mounted without difficulty on an assembled high-pressure fuel pump (1).
