Abstract
A sealing arrangement for a turbomachine, including a seal carrier element, an integral annular body element, and at least three protrusions. Guide blade element includes an opening that points radially inwardly for accommodating a protrusion of seal carrier element for spoke centering, and a radially inwardly extending sealing web. In the operating state, when there is sealing contact, each protrusion is accommodated in respective opening so that it is movable in axial direction A. Either seal carrier element includes a seal carrier web that extends in circumferential direction, with a sealing surface that points toward sealing web and that is offset in the axial direction, or sealing web of guide blade element extending in circumferential direction includes a sealing surface that points toward seal carrier web, and that is offset relative to an axial rear face of opening.
