Abstract

Vanne comportant un dispositif d'obturation à action rapide. Ce dispositif d'obturation à action rapide, notamment destiné à contrôler l'échappement hors d'une enceinte d'un fluide sous pression et éventuellement températures élevées est caractérise en ce qu'il comprend en combinaison un clapet d'obturation et un ensemble coaxial de commande à cylindre et piston utilisant les effets antagonistes de la pression du fluide de commande, et en ce que ledit ensemble de commande se trouve agencé à l'intérieur de l'enceinte. Application à des têtes d'injection de vapeur surchauffée utilisées en prospection sismique.
