  • Patent number: 8608176
    Abstract: 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 that faces toward the area normally under higher pressure. In order to extend substantially the area of application of sealing arrangements with lip seals and by doing so, to make use of the sealing arrangement to achieve its advantages of being more economical, more durable also at pressure peaks, easier to install, and easier to maintain, also at higher pressures and pressure fluctuations, the lip seal (3, 8, 14, 15) on the side (5) facing the area with higher pressure is under a constant pressure that is higher than the highest pressure occurring inside the housing (1), and a gap (7, 10) that throttles the outflow is provided between this area and the inside of the housing.
