Abstract

Zu einer Druckausgleichsdichtung (110) gehören eine radial nach innen weisende Dichtungsfläche (116) und eine Statorgrenzfläche, die wenigstens eine Fläche aufweist, die mit einem Stator in Berührung steht. Weiter umfasst die Druckausgleichsdichtung (110) ein Reibungsverringerungsstrukturmerkmal. Das Reibungsverringerungsstrukturmerkmal weist einen auf der Dichtungsfläche (116) ausgebildeten Hohlraum auf. Der Hohlraum ist dazu eingerichtet, ein Fluid aufzunehmen, so dass eine auf die Druckausgleichsdichtung ausgeübte Normalkraft durch eine Kraft ausgeglichen wird, die durch einen Druck des Fluids erzeugt wird.
