Abstract

L'invention concerne un dispositif d'étanchéité permettant d'isoler, à l'arrêt, le compartiment interne d'un compresseur pour fluide nocif lorsque celui-ci est désaccouplé de ses moyens d'entraînement. Le dispositif d'étanchéité est commandé par des moyens magnétiques possédant deux états stables d'attraction magnétique qui correspondent respectivement à la position active d'obturation et à la position inactive d'obturation. L'invention trouve particulièrement son emploi sur les groupes constitués d'un moteur et d'un compresseur destinés au transfert des fluides nocifs ou toxiques. Génie militaire.
