A brush gasket for two co-operating components located opposite one another. The brush gasket has a carrier body for the brushes arranged on one of the two components to be sealed off relative to one another, for example, a stator and a rotor. The carrier body has a supporting wall for the brushes on the low-pressure side, in order to protect them against pressure-related deformation. On the second of the components, opposite the carrier body, there is an abrasion ring made of a material which is softer than the material of the brushes. The abrasion ring together with the brushes thus forms a gasket group.

DETAILED DESCRIPTION Accordingly, one object of the invention is to provide a novel brush gasket which, on the one hand, takes into account the thermal and rotor-dynamic conditions and those stipulated as a consequence of installation, but, on the other hand, makes it possible to have a smaller sealing gap in comparison with conventional brush gaskets.
This object is achieved by means of the features of the defining part of claim 1.
The features of the dependent claims describe advantageous embodiments of such a brush gasket.
