Title (EN) RETURN TUBE OF A FUEL FILTER ASSEMBLY OF A FUEL SYSTEM
(FR) TUBE DE RETOUR D'UN ENSEMBLE FILTRE À CARBURANT DANS UN SYSTÈME D'ALIMENTATION EN CARBURANT
Abstract:
(EN) A fuel filter assembly for filtering a fuel-liquid mixture comprises a filter cartridge and a return tube. The filter cartridge comprises a filter media and a housing. The filter media defines an open central region therein. The housing contains the filter media. The return tube extends into the central region of the filter media. The return tube collects and drains liquid from a bottom inner region of the filter media.
(FR) Un ensemble filtre à carburant destiné à filtrer un mélange carburant-liquide comprend une cartouche filtrante et un tube de retour. La cartouche filtrante comprend un milieu filtrant et un boîtier. Le milieu filtrant définit une région centrale ouverte à l'intérieur de celui-ci. Le boîtier contient le milieu filtrant. Le tube de retour s'étend dans la région centrale du milieu filtrant. Le tube de retour collecte et évacue le liquide à partir d'une région intérieure inférieure du milieu filtrant.
