Abstract

La présente invention concerne un appareil pour conférer une flottabilité à des objets immergés. L'appareil est composé de flotteurs 5 immergeables constitués par un élément en forme de sac en un matériau étanche à l'air, souple et muni sur sa partie externe d'un dispositif de fixation sur ledit objet, une conduite 6 pour alimenter de l'air sous pression dans le flotteur et une soupape 7 de régulation à pression différentielle dans lequel la soupape 7 amène de l'air sous pression dans le flotteur 5 à travers la conduite 6 lorsque la différence de pression entre l'intérieur du flotteur et l'extérieur est inférieure à une valeur prédéterminée et dans lequel, lorsque la différence est supérieure, la soupape 7 évacue dans l'eau l'air se trouvant à l'interieur du flotteur 5. Cet appareil est utilisé pour tirer des pipe-lines dans l'eau.
