Abstract

L'invention concerne des systèmes de pompage associés de façon permanente aux ballasts d'un bateau-citerne à plusieurs ballasts séparés. Le système de l'invention comprend essentiellement une pompe prévue pour transporter de l'eau de lestage dans des directions opposées le long d'un seul trajet Une direction va de la mer au fond du ballast en passant par une première soupape et une première et une seconde ramifications, et l'autre direction va du ballast à la mer en suivant soit un trajet direct passant par la seconde et la première ramifications et la première soupape, soit un trajet indirect passant par la seconde ramification, une troisième ramification et une seconde soupape associée, vers l'atmosphère au-dessus du niveau de la mer. Le système de l'invention assure une simplification de construction et de fonctionnement par rapport aux systèmes connus.
