Abstract
A device for reducing the sealing gap between a rotating component and a stationary component inside a rotary turbo-engine through which a flow passes axially and in which the rotating component and the stationary component each have a surface portion arranged separated by a sealing gap and providing sealing structures on at least one of the two surface portions, one of the sealing structures being an abradable planar sealing structure. The surface portion opposite the abradable planar sealing structure likewise has an abradable planar sealing structure, and the two sealing structures bound the sealing gap in a planar manner.
