Abstract: The invention relates to a sealing arrangement for a non-hermetic seal of a gap (11) between a stator and a rotor with a brush seal (13), wherein the brush seal (13) has a bristle package (14) with several bristles (15), the bristles are wound about a core element (16) and fixed to the core element (16), wherein the brush seal (13) is disposed at least sectionally in an accommodating space, which is bounded by a supporting element (18) and a covering element (19), and wherein the bristles (15) have sealing bristle sections (21), which are at an angle to the bristle shafts (20) and the ends of which run against a sealing surface (22) of the rotor (12). According to the invention, the covering element (19) has a support surface (23) at an end adjacent to the sealing bristle sections (21), wherein the supporting surface (23) contacts the bristle shafts (20) in a defined, locally limited region, so that the radial mobility of the sealing bristle sections (21) is limited in the direction of the rotor (12).

Abstract: A sealing arrangement, especially for a flow engine, for non-hermetically sealing a gap (12) between a rotor (10) and a stator (11), which comprises a seal having a plurality of sealing elements that are fixed to a sealing element support, said sealing element support being at least partially disposed in a receptacle (16) which is defined by a supporting element (17) and a cover element (18) is disclosed. The sealing element support is configured as a ring that is interrupted once or several times. Free ends (19, 20) of the sealing element support overlap in the area of interruptions in the circumferential direction. The contours of the supporting element (17) and the cover element (18) are adapted to the contours of the sealing element support and the sealing elements (15). At least one end (19, 20) of every part of the sealing element support is associated with an antirotation device (21, 22).

Abstract: An arrangement for a non-hermetic seal between a stator and a rotor of a turbomachine in the root region of guide blades belonging to the stator. The arrangement includes a brush sealing ring which is mounted on the guide blades via a spoke centering means and whose bristles together with a rotating sealing surface form a fluid barrier which is permeable in a defined manner. On the sealing side of lower pressure, a supporting ring for the bristles is arranged at a slight distance from the rotating sealing surface, and this supporting ring is integrally connected to the guide blade roots and can be segmented by parting seams. The spoke centering means is permeable to pressure, as a result of which the brush sealing ring is pressure-relieved axially, with the exception of the bristle area between the sealing surface and supporting ring.
