SEAL AND SEAL ARRANGEMENT FOR CONFINING LEAKAGE FLOWS BETWEEN ADJACENT COMPONENTS OF TURBO-MACHINES AND GAS TURBINES
First Claim
1. A seal for stemming leakage flows between adjacent components of turbomachines, the seal comprising:
- an elongated, thin-walled sealing element which is elastically deformable in at least one transverse direction and in cross section has the shape of a bent band;
an elongated, thin-walled cover element having a U-shaped cross section, the U-shape having legs and a base, the legs and the base delimiting a recess in which the sealing element is positioned;
wherein the sealing element has a relaxed state in which a portion of the sealing element is outside said recess.

Abstract
A seal for stemming leakage flows between adjacent components (9, 20), especially of a gas turbine, has an elastically deformable, thin-walled sealing element (1) and a thin-walled cover element (13) which is U-shaped in cross section and between its legs (15) and its base (14) partially accommodates the sealing element (1). The legs (15) of the cover element (13) are arranged in the sealing arrangement, which features the seal, between two oppositely disposed walls (28) of the other component (9) in a movable manner relative to these walls (28) which, together with the sealing surface (8) of the other component (9), form a groove (27) which is U-shaped in cross section. Forces, which act laterally upon the seal, are absorbed by the cover element (13) and via the legs (15) are diverted into the other component (9) so that the integrity of the seal is maintained even in the case of lateral forces.

15. A sealing arrangement for stemming leakage flows between adjacent components of turbomachines, the sealing arrangement comprising:
-
first and second adjacent components of a turbomachine each having a wall, the walls together delimiting a space, each of said walls defining one of two oppositely disposed sealing surfaces; wherein a first component of said two adjacent components comprises two oppositely disposed walls, said oppositely disposed walls forming a U-shaped groove with the wall of the second component; a seal having an elongated, thin-walled sealing element which is elastically deformable in at least one transverse direction and having a cross sectional shape of a bent band; wherein the seal is arranged in the space in a pretensioned manner in the at least one transverse direction in such a way that the at least one transverse direction extends perpendicularly to the two oppositely disposed sealing surfaces; an elongated, thin-walled cover element, the cover element being U-shaped in cross section, the U-shape comprising two legs, a base, and a recess between the legs and the base in which the sealing element is positioned; wherein, in a relaxed state of the sealing element, a portion of the sealing element is outside of the recess; wherein the two legs are arranged between the two oppositely disposed walls of the first component, the two legs being movable relative to the two oppositely disposed walls. - View Dependent Claims (16, 17, 18, 19, 20, 21)
