Abstract

The invention relates to a brush seal for sealing a gap between a rotor and a stator, with at least one brush ring, comprising a number of sealing brushes and at least two annular brush ring carriers, running in the circumferential direction of the rotor. Each brush ring is fixed between a first front face of a first brush ring carrier and a second front face of a second brush ring carrier, whereby the second brush ring carrier is directly axially and radially fixed to the first brush ring carrier.
