Abstract:
(DE) Bei einer zur Montage in einem Kraftstoffbehälter eines Kraftfahrzeuges vorgesehenen Fördereinheit (1) mit einer eine Pumpenwand (7) aufweisenden Pumpe (3) ist ein Filterelement (4) gegen die Pumpenwand (7) vorgespannt. Hierfür ist ein Gehäuse (5) der Fördereinheit (1) einteilig mit einem Spannelement (18) gefertigt. Das Spannelement (18) weist zum Hintergreifen eines Randes (19) des Filterelementes (4) eine Umbördelung (20) auf. Hierdurch ist die Fördereinheit (1) besonders kostengünstig herstellbar.
(EN) The invention relates to a delivery unit (1) which is assembled in the fuel tank of an automobile, comprising a pump (3) with a wall (7) and a filter element (4) which is prestressed against the wall (7) of the pump. The housing (5) of the delivery unit (1) is manufactured as a single piece with a clamping element (18). The clamping element (18) has a flanged border (20) which clamps one edge (19) of the filter element (4) from behind. This enables the delivery unit (1) to be produced at a particularly low cost.
(FR) L'invention concerne une unité de refoulement (1) destinée à être montée dans le réservoir de carburant d'une automobile. Cette unité comprend une pompe (3) présentant une paroi (7) et un élément filtrant (4) précontraint contre la paroi (7) de la pompe. A cet effet, un boîtier (5) de l'unité de refoulement (1) est réalisé d'un seul tenant avec un élément de serrage (18). Ce dernier (18) présente un bord rabattu (20) destiné à enserrer un bord (19) de l'élément filtrant (4) depuis l'arrière. Cette unité de refoulement est de ce fait particulièrement économique à produire.
