Abstract

Un ensemble garniture d'étanchéité comprend un mandrin de garniture d'étanchéité et un élément d'étanchéité placé autour du mandrin d'étanchéité. Un manchon de récupération supérieur est placé autour du mandrin de garniture d'étanchéité et s'étend entre le mandrin de garniture d'étanchéité et une extrémité supérieure de l'élément d'étanchéité, et un manchon de récupération inférieur est placé autour du mandrin de garniture d'étanchéité et s'étend entre le mandrin de garniture d'étanchéité et une extrémité inférieure de l'élément d'étanchéité. Un ensemble de renfort supérieur est placé mobile autour du manchon de récupération supérieur et est adjacent à l'extrémité supérieure de l'élément d'étanchéité. Un ensemble de renfort inférieur est placé mobile autour du manchon de récupération inférieur. L'ensemble de renfort inférieur présente un ensemble anneau de renfort inférieur conçu pour entourer une surface extérieure de l'extrémité inférieure de l'élément d'étanchéité. Un manchon de récupération est sélectivement mobile par rapport à l'ensemble anneau de renfort inférieur et conçu pour rétracter au moins partiellement l'ensemble anneau de renfort inférieur.
