Abstract

Le dispositif d'étanchéité comprend principalement un joint 12 à deux lèvres d'étanchéité 13 et 14 et deux joints à lèvres simples 18 et 17. En fonctionnement normal l' étanchéité est assurée par ces joints. Lorsque l'ensemble est immergé sous l'eau, l'étanchéité peut être temporairement améliorée en alimentant le passage 27 par le conduit 23 en air comprimé.
