A sealing device 4 for sealing against e.g. rotatable shafts 3, tubes 1 or similar objects, comprises at least two annular sub-elements 5, 6 which are separated from each other by a cavity 8, 9. On their sides facing the cavity, said elements have one or more elastically resilient lips 10 abutting against the sealing object in question with a sealing pressure which increases with increasing pressure in a possible pressure medium present in the cavity. <IMAGE> |
