Sealing arrangement for a turbomachine, seal carrier element for the sealing arrangement, guide blade element, and turbomachine

A sealing arrangement for a turbomachine, the sealing arrangement comprising:

• a seal carrier element with an inlet coating at a radially inner end;
• an integral annular body element;
• and
• at least three protrusions for spoke centering of the seal carrier element radially within guide blade elements, with at least three respective openings for the at least three protrusions, the seal carrier element being configured so that the spoke centering is achieved via radial guiding of the at least three protrusions in the at least three openings, each protrusion of the at least three protrusions, in each case in an axial direction, having a front face in a flow direction and a rear face in the flow direction,
• the guide blade element including the opening pointing radially inwardly for accommodating one of the at least three protrusions of the seal carrier element for spoke centering, and including a radially inwardly extending sealing web forming a radially innermost section of the guide blade element,
• when there is sealing contact between the seal carrier element and the guide blade element, each protrusion being movably accommodated in an axial direction in the respective opening, and
• the seal carrier element including a seal carrier web extending in a circumferential direction, with a sealing surface pointing toward the sealing web offset relative to axial front faces as well as axial rear faces of the protrusions in the axial direction, or the sealing web extending in the circumferential direction and including a web sealing surface pointing toward the seal carrier web and offset relative to an axial rear face of the opening in the axial direction.
