A sealing arrangement for the sealed leadthrough of rotating shafts (2) through housing bores of housings (1) comprises at least one lip seal (3, 8, 14, 15) with a sealing lip which faces toward the region with normally higher pressure. In order to significantly widen the field of use of sealing arrangements with lip seals, and to thereby obtain, even in the event of relatively high pressures and pressure fluctuations, the advantages of said sealing arrangements with lip seals with regard to greater economic viability, better durability even in the event of pressure peaks, simpler installation and simpler servicing, the lip seal (3, 8, 14, 15) is acted on, on the side (5) which faces toward the region with the higher pressure, with a constant pressure which is higher than the highest pressure occurring within the housing (1), and a gap (7, 10) which throttles the outflow is provided between said region and the housing interior. |
