Abstract

Filter für Kraftstoffentnahmevorrichtungen von Kraftfahrzeugen werden bei tiefen Temperaturen durch Paraffinausscheidungen der Kraftstoffe zugesetzt, so daß eine störungsfreie Versorgung des Motors mit Kraftstoff nicht gewährleistet ist. Die neue Kraftstoffentnahmevorrichtung soll auch bei tiefen Temperaturen eine zuverlässige Versorgung gewährleisten, insbesondere soll das Kaltstartverhalten verbessert werden.
Die erfindungsgemäße Kraftstoffentnahmevorrichtung (1) besitzt eine bis in den Filter (8) geführte Rücklaufleitung (5), deren Kraftstoffstrom in mehrere Teilströme (T1,T2) aufgeteilt wird. Indem mindestens ein Teilstrom (T1) des vom Motor kommenden, heißen Rücklaufs auf die Filterfläche (11) gelenkt wird, werden am Filter (8) angelagerte Paraffinabscheidungen in diesem Bereich aufgelöst, so daß auch bei tiefen Temperaturen Kraftstoff durch den Filter (8) angesaugt wird.
