Abstract:
1. A turbomachine comprising: a stator, a rotor, and an axial sealing device arranged between the stator and the rotor, wherein the sealing device has on the stator side a radially stepped sealing honeycomb contour with regions projecting and retracting in the direction of the rotor; a plurality of sealing fins on the rotor side projecting in the direction of the stator, each of the plurality of sealing fins engaging into adjacent retracting regions of the stator-side sealing contour; and at least one additional fin on the rotor side projecting in the direction of the stator, the at least one additional fin positioned between two adjacent sealing fins arranged on the rotor side and lying opposite a projecting region of the stator-side sealing contour; wherein at least one of the at least one additional fin, at least one of the plurality of sealing fins, or both, is arranged inclined radially and axially on the rotor; wherein a degree of inclination of the at least one additional fin, of the at least one sealing fin, or of both, is approximately 25° to 35°.
