Abstract

Disposición de estanqueidad de una turbomáquina axial para estanqueizar zonas en o junto a al menos dos piezas componentes estáticas de la turbomáquina, en donde las piezas componentes son axialmente desplazables una con relación a la otra, que comprende un elemento de estanqueidad (100) y una de las al menos dos piezas componentes estáticas de la turbomáquina, en donde el elemento de estanqueidad (100) está configurado de manera segmentada en la dirección periférica de la turbomáquina, caracterizada por que el elemento de estanqueidad (100) presenta una primera zona radial (1), configurada en forma de espiral o de gancho, que actúa de forma rigidizante, con una primera rigidez y una segunda zona radial (5) con una segunda rigidez, siendo la primera rigidez mayor que la segunda rigidez y estando la primera zona radial (1) como componente de fijación del elemento de estanqueidad fijada en una pieza componente estática de la turbomáquina.
