Abstract

Dans ce dispositif, les moyens d'actionnement des deux clapets sont constitués par un cylindre 25 unique dont la chambre est en communication avec la capacité 2 à protéger, à l'intérieur duquel est déplaçable un piston 26 dont la tige 27 est apte à venir en appui, lors d'un déplacement du piston dans le cylindre, à l'encontre de l'action de moyens élastiques 29 et sous l'effet de la pression régnant dans la capacité, sur une tige coaxiale 34, dont le déplacement est également réalisé à l'encontre de l'action de moyens élastiques, et sur Laquelle est monté un organe 36 apte, en fonction de la position de la tige, à agir sur les tiges 15, 22 des deux clapets 14, 20 associés respectivement à l'enceinte 13 reliant la capacité à protéger au cylindre 7 de commande et à l'enceinte 17 apte à mettre à l'atmosphère le cylindre de commande Application à l'équipement d'une chaudière
