Abstract

La présente invention a pour objet un dispositif pour le réglage de la dépression dans un système de conduite à dépression, en particulier pour des installations de traite. Ce dispositif comporte un carter 1, qui peut être raccordé à une conduite à dépression 3 et dans lequel est disposée une soupape principale avec une chambre de soupape principale, qui comporte un siège de soupape 5, et des ouvertures d'entrée d'air 6 dans ses parois extérieures, ainsi qu'un corps 7 de soupape principale qui est relié par l'intermédiaire d'une tige de soupape 8 à une membrane 9, qui sépare la chambre de soupape principale d'une chambre de commande qu'on peut soumettre à une dépression dépendant de la dépression régnant dans la conduite à dépression, ainsi qu'une soupape auxiliaire disposée dans le carter 1, influençant la dépression dans la chambre de commande et comportant un corps de soupape auxiliaire 11 qui est assemblé à une membrane auxiliaire 12 qui sépare les deux chambres auxiliaires, dont la première communique avec la conduite à dépression 3 et la deuxième avec l'espace extérieur, et la différence de pression ainsi obtenue produisant une force soulevant le corps de soupape auxiliaire du siège de soupape à l'encontre de la force réglable exercée par un ressort hélicoïdal 15.
