  • Publication number: 20100119368
    Abstract: A sealing device for providing sealing between a casing and a shaft rotatably mounted in the casing. The device includes first and second annular lip gaskets for placing axially side by side between the casing and the shaft. A stream of pressurized gas is delivered into an annular casing defined by the first lip gasket, the second lip gasket, and an outside surface of the shaft, such that during rotation of the shaft, the gas stream is suitable for causing at least one of the two lip gaskets to lift off a little from the outside surface of the shaft in order to flow out from the cavity.
