Title
(DE) Zahnradpumpe, insbesondere Ölpumpe
Abstract
(DE)

Die Erfindung betrifft eine elektromotorische Innenzahnradpumpe (1) für ein Kraftfahrzeug, mit einem Rotorgehäuse (2) mit zylindrischer Innenwandfläche (3), und mit einem in das Rotorgehäuse (2) aufgenommen Pumpenrotor (9) mit einem exzentrisch angeordneten außenverzahnten Innenring (12)) und mit einem diesen umgebenden innenverzahnten Außenring (10) sowie mit einer Außenlauffläche (20), wobei die Innenwandfläche (3) des Rotorgehäuses (2) ein Schmiermittelkanal (18) und in die Außenlauffläche (20) des Außenrings (10) mindestens eine Nut (21) eingebracht ist, so dass der Außenring (10) im Zuge dessen Drehbewegung das Schmiermittel aus dem Schmiermittelkanal (18) zwischen die Außenlauffläche (20) und die Innenwandfläche (3) des Rotorgehäuses (2) fördert. embedded image
