Abstract
In fluid machines frequently gaps between movable and stationary structural parts have been sealed off. Frequently so-called labyrinth packings are used, whereby sealing strips brush against the opposite structural part. To this end, a brush layer is configured as a porous coating that can be detached from the opposite structural part. The inventive system can be advantageously used in virtually any fluid machines.
