Abstract

Una junta para turbomáquinas (20) que comprende por lo menos un primer elemento alargado curvo que tiene una parte de acoplado (22) configurada para cooperar con un ensamble tubular (30) para mantener la junta en su lugar en el ensamble tubular (30), y una superficie exterior configurada para sellar contra un alojamiento exterior proporcionado para alojar el ensamble tubular (30), el primer elemento curvo comprende un primer y un segundo extremos libres, el primer extremo libre proporciona un primer reborde que sobresale y el segundo extremo libre proporciona un segundo reborde que sobresale, el primer reborde que sobresale se configura para sobreponerse con el segundo reborde que sobresale del primer elemento alargado curvo o con un segundo reborde que sobresale de un segundo elemento idéntico de manera funcional al primero, para que, cuando la junta está en uso, se obtenga un sello en esa parte de la junta que tiene rebordes que sobresalen.
