Each sealing assembly includes at least two radial shaft sealing rings arranged with a mutual axial spacing so as to form at least one chamber. Respective radial shaft sealing rings are arranged such that their respective sealing lips are directed away from the respective chamber. A gas source having a gas pressure can impinge on the respective chamber.
