Claim 7:
8. A turbomachine comprising:
a stator configured to guide a fluid passing therethrough;
a rotor disposed in the stator configured to rotate with the fluid passing through the stator,
a tie rod extending in an axial direction from upstream to downstream; and
wherein the stator comprises:
a casing;
first and second vane carriers disposed on a radially inner side of the casing so as to be arranged adjacent to each other along the axial direction;
vanes respectively coupled to inner circumferential surfaces of the first and second vane carriers; and
a sealing assembly formed in a ring shape, encircling the tie rod, defining a circumferential direction that follows a contour of the sealing assembly and sealing a gap between the first and second vane carriers,
wherein the sealing assembly comprises a plurality of sealing bodies configured to be coupled to each other in the circumferential direction to form the sealing assembly,
wherein a sealing body of the plurality of sealing bodies is formed in a segmented ring shape, is configured to be inserted into an insertion hole of the second vane carrier adjacent to the first vane carrier, and extends from a first circumferential end to a second circumferential end in the circumferential direction,
wherein the sealing body includes a first body art and a second body part, both are substantially rectangular when viewed from the circumferential direction, the second body part protrudes outward from the first body part in the radial direction, a surface of the second body part facing the first component forms a substantially right angle with an outermost radial surface of the first body part, the substantially right angle spans from the first circumferential end to the second circumferential end, and a surface of the second body part facing downstream in the axial direction flushes with a surface of the first body part facing downstream in the axial direction,
wherein a sealing protrusion is formed on the first circumferential end of the sealing body, protrudes toward the circumferential direction from the sealing body, and is configured to be inserted into a sealing groove formed on the second circumferential end of an adjacent sealing body,
wherein an outermost radial surface of the second body part is positioned radially outward compared to the outermost radial surface of the first body part, and the outermost radial surface of the first body part is positioned radially outward compared to an outermost radial surface of the sealing protrusion.
