CA 2317933

A marine cable includes chambers forming a necklace float. For filling, degassing the chambers and for connecting two successive chambers, the cable includes an intervention orifice between the chambers and with which the chambers communicate. Connection of the chambers to the intervention orifice is controlled by two valve mechanisms which each include an obturator spring-loaded against a communication opening and a guide rod which, when the obturator closes the opening, lies partly in the intervention orifice so that it is possible to push back the rods of the valve mechanisms from the intervention orifice for selective connection of the intervention orifice to one or the other of the two chambers or with both at the same time.

Câble marin comportant plusieurs chambres formant flotteur en chapelet, ainsi que des moyens permettant le remplissage, dégazage desdites chambres et des moyens permettant la mise en communication de deux chambres successives, lesdits moyens comportant un orifice d'intervention qui est disposé entre lesdites chambres et avec lequel lesdites chambres communiquent, caractérisé en ce que la mise en communication desdites chambres avec ledit orifice d'intervention est commandée par deux mécanismes à soupape qui comportent chacun un obturateur repoussé par des moyens ressorts contre une ouverture de communication et une tige de guidage qui, lorsque l'obturateur ferme ladite ouverture, s'étend en partie dans l'orifice d'intervention, de sorte qu'il est possible de repousser les tiges des mécanismes à soupape à partir de l'orifice d'intervention pour sélectivement mettre en communication ledit orifice d'intervention avec l'une ou l'autre des deux chambres ou avec les deux en même temps.
