Abstract

Pour assurer l'étanchéité du passage d'un arbre déplaçable longitudinalement par rapport à une paroi (11), on a engagé, dans la forure de la paroi (11) un corps d'étanchéité en une pièce (13), en polytétrafluoréthylène. Ce corps d'étanchéité présente un tronçon tubulaire (15) s'avançant axialement vers le coté haute pression et qui est entouré de bagues de serrage (18). Ainsi est obtenue une application, dépendant de la pression, du tronçon (15) qui forme l'intervalle d'étanchéité (21), avec l'arbre (10). Le dispositif convient pour de forte pression allant jusqu'à environ 400 bars.
