Sealing device for the gap between rotor and stator of a turbo machine has brush seal holder with support elements having elastic yield in axial and radial direction

摘要

A brush seal holder (7) on the stator (2) has support elements (12), which are elastically yielding in axial and radial direction. The support elements are formed, so that a force directed towards the holder and introduced radially into the elements, combines an elastic radial movement in a section facing the rotor (1), with an elastic axial movement of the section in a direction away from the sealing brush (8).
