Abstract

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.
