Abstract
L'invention concerne une unité de dépression permettant d'uniformiser la pression entre l'atmosphère ambiante et un réservoir de navire-citerne. Ladite unité de dépression comprend un logement de soupape (10) doté d'une première ouverture (12) permettant à ce logement de soupape (10) de communiquer avec le réservoir, et d'une seconde ouverture (24) comprenant un siège (30) de corps de soupape (40) configuré de façon à être transporté dans ledit logement de soupape (10) afin de laisser entrer l'air dans ledit réservoir; et un mécanisme (100) configuré de façon à empêcher l'entrée d'eau de mer dans le logement de soupape (10) en cas d'accident, le navire-citerne étant partiellement immergé dans l'eau de mer. Ledit mécanisme comprend une première partie (160) mobile agencée à l'extérieur du logement de soupape (10) dont le déplacement peut être commandé par la pression liquide de l'eau de mer, et une seconde partie (150) pouvant être introduite dans le logement de soupape (10) et couplée mobile à ladite première partie (160) mobile. L'invention est caractérisée en ce que la seconde partie (150) mobile configurée de façon à venir en about au corps de soupape (40) au moyen d'un déplacement plus important de la première partie (160) mobile, ce qui ramène de corps de soupape (40) contre ledit siège.
