Abstract

Eine Vorrichtung zur Umleitung eines zwischen einem Stator (102) und einem Rotor (104) fließenden Leckagestroms (106) umfasst ein Dichtelement (112) zum Unterbrechen des Leckagestroms (106), eine an dem Rotor (104) angeordnete Austrittsöffhung (114) und eine Führung (116, 132), die ausgebildet ist, um den Leckagestrom (106) an dem Dichtelement (112) vorbei zu der Austrittsöffhung (114) zu führen.
