Abstract

L'invention concerne un dispositif d'étanchéité pour rendre étanche une traversée d'arbre (1) dans une cloison étanche (2) d'un navire. Le dispositif d'étanchéité comprend, un carter annulaire étanche (4) divisé dans le sens radial, au moins deux bagues d'étanchéité (5) disposées dans des chambres annulaires du carter étanche (4) de part et d'autre d'un espace annulaire (6) du carter étanche (4) alimenté en fluide d'arrêt, de façon à pouvoir être déplacées dans le sens radial et à assurer l'étanchéité à la surface frontale, et un système pour l'amenée du fluide d'arrêt. Les bagues d'étanchéité (5) sont divisées dans le sens radial et constituées de segments de joint d'étanchéité (9) dont les bords sont raccordés bout-à-bout et qui sont sollicités par un ressort flexible (10) monté à la périphérie des segments. Le carter étanche (4) est raccordé à la surface frontale libre d'un soufflet dont la face arrière est fixée sur la cloison étanche (2).The invention relates to a sealing device for sealing a shaft passage (1) in a watertight bulkhead (2) of a ship. The sealing device comprises, a sealed annular casing (4) divided in the radial direction, at least two sealing rings (5) arranged in annular chambers of the sealed casing (4) on either side of a annular space (6) of the sealed housing (4) supplied with shut-off fluid, so as to be able to be displaced in the radial direction and to ensure the sealing at the front surface, and a system for the supply of the fluid from stop. The sealing rings (5) are radially divided and consist of sealing segments (9) whose edges are connected end to end and which are biased by a flexible spring (10) mounted at the periphery of segments. The sealed casing (4) is connected to the free front surface of a bellows, the rear face of which is fixed to the sealed partition (2).
