Abstract
The invention relates to a sealing arrangement for a non-hermetic seal of a gap () between a stator and a rotor with a brush seal (), wherein the brush seal () has a bristle package () with several bristles (), the bristles are wound about a core element () and fixed to the core element (), wherein the brush seal () is disposed at least sectionally in an accommodating space, which is bounded by a supporting element () and a covering element (), and wherein the bristles () have sealing bristle sections (), which are at an angle to the bristle shafts () and the ends of which run against a sealing surface () of the rotor (). According to the invention, the covering element () has a support surface () at an end adjacent to the sealing bristle sections (), wherein the supporting surface () contacts the bristle shafts () in a defined, locally limited region, so that the radial mobility of the sealing bristle sections () is limited in the direction of the rotor ().
