(FR) POMPE À CARBURANT DESTINÉE À TRANSPORTER DU CARBURANT D'UN RÉSERVOIR VERS UN MOTEUR À COMBUSTION INTERNE
Abstract
(DE) Gegenstand der Erfindung ist eine Kraftstoffpumpe (1) zum Fördern von Kraftstoff aus einem Vorratsbehälter zu einer Brennkraftmaschine mit einem Gehäuse, mindestens einem in dem Gehäuse angeordneten Laufrad (6,26), wobei das Laufrad mindestens einen Kranz von zueinander beabstandet angeordneten Schaufeln (10,31) aufweist, einem das Laufrad über eine Welle (13) antreibenden Elektromotor, der als Axialfeldmotor ausgebildet ist und einen Rotor (5,32) und einen Stator (14) besitzt, dessen Rotor Permanentmagnete (11,33) aufweist und dass den Permanentmagneten gegenüberliegend Wicklungen (18) tragende Spulenkörper (17) im Abstand zur Rotorachse und in gleichmäßigen Winkelabständen fest in dem Stator angeordnet sind. Die Spulenkörper (17) sind bezogen auf ihre Längsausrichtung parallel zur Welle des Elektromotors angeordnet.
(EN) The invention relates to a fuel pump (1) for delivering fuel from a reservoir to an internal combustion engine. Said pump comprises a casing, at least one impeller (6, 26) arranged in the casing, said impeller comprising at least one ring of interspaced vanes (10, 31). The pump further comprises an electric motor that drives the impeller via a shaft and that is configured as an axial field motor and that has a rotor and a stator. The rotor of said electric motor has permanent magnets and the coil formers carrying windings that are opposite the permanent magnets are stationarily arranged in the stator at a distance to the rotor axis and at even angular distances. The coil formers are arranged in parallel to the shaft of the electric motor with respect to their longitudinal orientation.
(FR) L'invention concerne une pompe à carburant (1) destinée à transporter du carburant d'un réservoir vers un moteur à combustion interne, comportant un carter; au moins une roue à aubes(6, 26) disposée dans le carter, présentant au moins une couronne d'aubes (10, 31) espacées les unes par rapport aux autres; et un moteur électrique entraînant la roue à aubes au moyen d'un arbre (13), conçu en tant que moteur à champ axial, présentant un rotor (5, 32) et un stator (14). Le rotor est pourvu d'aimants permanents (11, 33) et des corps de bobine (17) portant des enroulements (18) sont disposés fixes dans le stator, en face des aimants permanents, à distance de l'axe de rotor, et à des angles réguliers. Les corps de bobine (17) sont disposés parallèles à l'arbre du moteur électrique en ce qui concerne leur orientation longitudinale.
