Title
(DE) AGGREGAT ZUM FÖRDERN VON KRAFTSTOFF
(EN) FUEL-FEED UNIT
(FR) UNITE D'ALIMENTATION EN CARBURANT
Abstract
(DE)
Die Erfindung betrifft ein Aggregat zum Fördern von Kraftstoff aus einem Vorratstank zur Brennkraftmaschine eines Kraftfahrzeuges mit einem elektrischen Antriebsmotor und einer von diesem angetriebenen Strömungspumpe (11), die ein mit einem Aggregatgehäuse (32) fest verbundenes, eine Pumpenkammer (17) bildenes Pumpengehäuse (16, 21) hat, in dem von dem Antriebsmotor bewegte Fördermittel (12) umlaufen, wobei an dem wenigstens einen die Pumpenkammer (17) begrenzenden Gehäuseteil (16, 21) ein aus verschleißfestem Material ausgebildeter Einsatz (51) angeordnet ist, der zumindest einen Teil einer Kammerwand bildet, die die Pumpenkammer (17) in Richtung der Drehachse (15) der Fördermittel (12) begrenzt.
(EN)
The invention concerns a unit for feeding fuel from the fuel tank of a vehicle to the engine, said unit set comprising an electric motor driving a flow pump (11) whose housing (16, 21) is rigidly connected to the housing (32) of the set and forms the pump chamber (17) in which the feeding means (12) driven by the drive motor rotates. An insert (51) made of wear-resistant material is fitted on at least one of the parts of the housing (16, 21) surrounding the pump chamber (17), the insert forming at least part of one of the wall which delimits the pump chamber (17) in the direction of the axis of rotation (15) of the feeding means (12).
(FR)
L'invention concerne une unité permettant d'alimenter en carburant le moteur à combustion interne d'une automobile, avec du carburant provenant d'un réservoir. Cette unité comprend un moteur d'entraînement électrique et une pompe d'écoulement (11) actionnée par ledit moteur, qui présente un carter (16, 21). Ce carter (16, 21), dans lequel tournent des éléments de refoulement (12) déplacés par le moteur d'entraînement, forme une chambre de pompe (17) et est solidarisé avec le boîtier (32) de l'unité. Sur au moins une des parties du carter (16, 21) qui délimite la chambre de la pompe (17), il est prévu un insert (51) réalisé dans un matériau résistant à l'usure, qui forme au moins une partie d'une paroi délimitant la chambre de pompe (17) dans le sens de l'axe de rotation (15) des éléments de refoulement (12).
