Abstract

Es sind bereits Kraftstoffversorgungssysteme bekannt, bei denen am Gehäuse des Kraftstoff-Filters ein Kraftstoffdruckregler angeordnet ist. Eine solche Anordnung kann unter Umständen ein schwingfähiges System bilden, wodurch es zu Geräuschproblemen kommen kann. Aufgabe der Erfindung ist es, ein Kraftstoffversorgungssystem zu schaffen, bei dem am Kraftstoff-Filtergehäuse ein Kraftstoffdruckregler angeordnet ist und bei dem die bei einem Fahrzeugbetrieb auftretenden Geräusche vermindert sind.
Dies wird dadurch erreicht, daß an einem Abschnitt (9, 10) zwischen dem Kraftstoff-Filter (6) und dem Verbrennungsmotor (17) und/oder dem Kraftstoffdruckregler (12) mindestens eine Drosselvorrichtung (11, 49, 59) angeordnet ist.
