Abstract
A sealing arrangement includes a housing component, a shaft at least partially accommodated by the housing component, and a plurality of sealing elements, which can be moved along the longitudinal axis of the shaft for sealing the intermediate space between the housing component and the shaft. The shaft includes a section that extends in the longitudinal direction of the shaft and has a shaft diameter that is tapered in steps. The sealing elements can be moved from a first position, in which a first sealing element lies against a first step, to further positions, in which additionally at least one further sealing element lies against one further step per sealing element.
