Title (DE) INNENZAHNRADPUMPE
(EN) INTERNAL GEAR PUMP
(FR) POMPE À ENGRENAGE INTÉRIEUR
Abstract:
(DE) Eine Innenzahnradpumpe (14) weist einen um eine Antriebsachse (104) drehbar antreibbaren Innenrotor (100) auf. Es wird vorgeschlagen, dass der Innenrotor (100) mittels einer in einer Brennkraftmaschine (12) lagerbaren oder gelagerten Welle (48) antreibbar ist, welche einen um die Antriebsachse (104) des Innenrotors (100) drehbaren Wellenabschnitt (114) zum Antrieb des Innenrotors (100) aufweist.
(EN) The invention relates to an internal gear pump (14) which comprises an inner rotor (100) which can be driven to rotate about a driving axis (104). The inner rotor (100) can be driven by a shaft (48) which can be or is mounted in an internal combustion engine (12) and which has a shaft section (114) for driving the inner rotor (100), said shaft section (114) being rotatable about the driving axis (104) of the inner rotor (100).
(FR) L'invention concerne une pompe à engrenage intérieur (14) présentant un rotor intérieur (100) pouvant être entraîné en rotation autour d'un arbre moteur (104). Il est prévu que le rotor intérieur (100) puisse être entraîné au moyen d'un arbre (48) pouvant être monté ou étant monté dans un moteur à combustion interne (12), ledit arbre présentant un segment (114) pouvant tourner autour de l'arbre moteur (104) du rotor intérieur (100), afin d'actionner le rotor intérieur (100).
