Title (EN) FUEL PUMP
(FR) POMPE À CARBURANT
(DE) KRAFTSTOFFPUMPE
Abstract:
(EN) A fuel pump for a fuel injection system of an internal combustion engine comprises a pump housing and a fastening section (16) which is present on the pump housing for fastening the fuel pump to a base, in particular an engine block, wherein the fastening section (16) has a through opening (22) for receiving a holding element for a fastening means, in particular a screw, characterized in that at least one radially inwardly directed projection (32) is present at least in an end region (30) of the through opening (22), which end region (30) faces the base in the installed position.
(FR) L'invention concerne une pompe à carburant pour un système d'injection de carburant d'un moteur à combustion interne, cette pompe comprenant un corps de pompe et une partie de fixation (16) située sur le corps de pompe pour fixer la pompe à carburant sur une base, en particulier un bloc moteur. La partie de fixation (16) présente une ouverture de passage (22) destinée à recevoir un élément de retenue pour un moyen de fixation, en particulier une vis. L'invention se caractérise en ce qu'au moins une partie saillante (32) dirigée vers l'intérieur radialement est présente dans une zone d'extrémité (30) de l'ouverture de passage (22), laquelle zone d'extrémité fait face à la base en position de montage.
(DE) Eine Kraftstoffpumpe für ein Kraftstoff-Einspritzsystem einer Brennkraftmaschine umfasst ein Pumpengehäuse und einen am Pumpengehäuse vorhandenen Befestigungsabschnitt (16) zur Befestigung der Kraftstoffpumpe an einer Basis, insbesondere einem Motorblock, wobei der Befestigungsabschnitt (16) eine Durchgangsöffnung (22) zur Aufnahme eines Halteelements für ein Befestigungsmittel, insbesondere eine Schraube, aufweist, dadurch gekennzeichnet, dass mindestens in einem in Einbaulage der Basis zugewandten Endbereich (30) der Durchgangsöffnung (22) mindestens ein nach radial einwärts gerichteter Vorsprung (32) vorhanden ist.
