Title (EN) HIGH-PRESSURE FUEL PUMP
(FR) POMPE À CARBURANT À HAUTE PRESSION
(DE) KRAFTSTOFF-HOCHDRUCKPUMPE
Abstract:
(EN) A high-pressure fuel pump (10) comprises a pump housing (12), an inlet (14), a fuel filter device (50), a pumping section (38), and an outlet (46). The fuel filter device (50) has an annular base portion (52) and an overall at least approximately cylindrical filter portion (54) extending from the base portion (52). According to the invention, the filter device (50) is arranged in such a way that the fuel flows into the annular base portion (52) in the axial direction and flows out of the filter portion (54) at least also in the radially outward direction.
(FR) L'invention concerne une pompe à carburant à haute pression (10) qui comprend un carter de pompe (12), une entrée (14), un dispositif de filtration (50) de carburant, une section de refoulement (38) et une sortie (46). Le dispositif de filtration (50) de carburant comporte une section de base (52) annulaire et une section de filtration (54) globalement à peu près cylindrique s'étendant depuis la section de base. L'invention propose que le dispositif de filtration (50) soit disposé de telle manière que le carburant afflue axialement dans la section de base (52) annulaire et sort au moins également vers l'extérieur radialement de la section de filtration (54).
(DE) Eine Kraftstoff-Hochdruckpumpe (10) umfasst ein Pumpengehäuse (12), einen Einlass (14), eine Kraftstoff-Filtereinrichtung (50), einen Förderabschnitt (38) und einen Auslass (46). Die Kraftstoff-Filtereinrichtung (50) weist einen ringförmigen Basisabschnitt (52) und einen sich von dieser aus erstreckenden insgesamt mindestens in etwa zylindrischen Filterabschnitt (54) auf. Es wird vorgeschlagen, dass die Filtereinrichtung (50) so angeordnet ist, dass der Kraftstoff axial in die ringförmige Basisabschnitt (52) einströmt und mindestens auch nach radial außen aus dem Filterabschnitt (54) ausströmt.
