Title (DE) KRAFTSTOFFHOCHDRUCKPUMPE
(EN) HIGH-PRESSURE FUEL PUMP
(FR) POMPE À CARBURANT HAUTE PRESSION
Abstract:
(DE) Eine Kraftstoffhochd ruckpumpe umfasst eine Gehäusewand eines Pumpengehäuses (40) und eine Dämpfungsvorrichtung (32) zum Dämpfen einlassseitiger Druckpulsationen durch eine Variation eines Dämpfungsvolumens (38) mittels einer elastisch beweglichen Wand (66). Es wird vorgeschlagen, dass wenigstens ein Abschnitt der elastisch beweglichen Wand (66) durch wenigstens einen Teil eines mantelartigen Bereichs (60) der Gehäusewand und/oder wenigstens einen Teil eines Dichtungsträgers (44) gebildet wird und der Abschnitt so ausgebildet ist, dass er mindestens einen überwiegenden Anteil zur Variation des Dämpfungsvolumens (38) beiträgt.
(EN) The invention relates to a high-pressure fuel pump comprising a housing wall of a pump housing (40) and a damping device (32) for damping inlet-side pressure pulses by varying a damping volume (38) by means of an elastically deformable wall (66). According to the invention, at least one section of the elastically deformable wall (66) is formed from at least one part of a jacket-like area (60) of the housing wall and/or at least one part of a sealing support (44) and the section is embodied such that it comprises at least one main part for varying the damping volume (38).
(FR) L'invention concerne une pompe à carburant haute pression comprenant une paroi de carter (40) et un dispositif d'amortissement (32) qui assure l'amortissement de pulsations de pression côté entrée par la variation du volume d'amortissement (38) à l'aide d'une paroi (66) mobile par élasticité. Selon l'invention, au moins une section de la paroi (66) mobile par élasticité étant formée d'au moins une partie d'une zone de type latérale (60) de la paroi de carter et/ou d'au moins une partie d'un porte-joint (44), et la section étant conçue de manière à contribuer au moins dans une mesure prépondérante à la variation du volume d'amortissement (38).
