Title
(DE) INNENZAHNRAD-KRAFTSTOFFPUMP
(EN) INTERNAL GEAR FUEL PUMP
(FR) POMPE A CARBURANT A ROUE A DENTURE INTERIEURE
Abstract
(DE) Die Erfindung bezieht sich auf eine Kraftstoffpumpe mit einem Gehäuse (6), einem in dem Gehäuse (6) angeordneten Elektromo tor (1), bestehend aus einem Stator (7) und einem eine Welle (9) aufweisenden Rotor (8) , wobei die Welle (9) sich bis in dem Bereich einer Pumpstufe (2) erstreckt und diese durch- dringt. Die Pumpstufe (2) ist als G-Rotorstufe ausgebildet. Die Welle (9) des Elektromotors (1) weist zumindest in dem Bereich (10) in dem die Welle (9) einen Innenläufer (15) der G-Rotorstufe (2) durchdringt an ihrem Umfang zumindest zwei Abflachungen (16, 17) auf, während der Innenläufer (15) der Rotorstufe (2) eine ebenso gestaltete Ausnehmung (18) aufweist .
(EN) The invention relates to a fuel pump comprising a housing (6), an electric motor (1) arranged in said housing (6) and provided with a stator (7) and a rotor (8) having a shaft (9). The shaft (9) extends to the area of a pump stage (2) and passes therethrough. The pump stage (2) is configured as a G-rotor stage. The shaft (9) of the electric motor (1) has, on its periphery, at least two flattened portions (16, 17) at least in the area (10) in which the shaft (9) passes through an inner rotor (15) of the G-rotor stage (2), whilst the inner rotor (15) of the rotor stage (2) has an identically configured recess (18).
(FR) L'invention concerne une pompe à carburant comportant un carter (6), un moteur électrique (1) logé dans le carter (6), composé d'un stator (7) et d'un rotor (8) présentant un arbre (9), l'arbre (9) s'étendant jusque dans la zone d'un étage de pompe (2) et traversant celui-ci. L'étage de pompe (2) est conçu en tant qu'étage de rotor G. l'arbre (9) du moteur électrique (1) présente au moins deux méplats (16, 17), au moins dans la zone (10) dans laquelle l'arbre (9) traverse un rotor intérieur (15) de l'étage de rotor G, sur sa périphérie, tandis que le rotor intérieur (15) de l'étage de rotor (2) présente une cavité correspondante (18).
