Abstract

The invention relates to a brush seal for sealing a rotor against a stator. A brush housing is provided for fastening brushes whose free ends are directed towards the stator or rotor. The brush housing is held on the rotor or stator and has a support plate. In the brush seal the free ends of the brushes are provided with a slide-ring to improve the sealing effect and reduce the wear.
