Abstract

Scrollvakuumpumpe (10) umfassend ein Pumpsystem (20), das ein feststehendes Spiralbauteil (30) und ein mit diesem pumpwirksam zusammenwirkendes bewegliches Spiralbauteil (40) umfasst, eine im Betrieb um eine Drehachse rotierenden Antriebswelle (22) mit einem Exzenterabschnitt (24) zum Antreiben des beweglichen Spiralbauteils (40), und einen elektrischen Antriebsmotor (24) für die Antriebswelle (22).In einem thermisch kalten Zustand des Pumpsystems (20) ist ein minimaler radialer Abstand (230) zwischen einer radial inneren Innenseite (214) einer Kreiswand (210) und einer radial inneren Innenwandung (222) einer Kreisnut (220) kleiner als ein minimaler radialer Abstand (232) zwischen einer radial äußeren Außenseite (214) der Kreiswand (210) und einer radial äußeren Außenwandung (224) der Kreisnut (220).
