Abstract

Dispositif à commande de pression comportant un boîtier, un soufflet de travail, un soufflet supplémentaire entourant celui-ci, ces deux soufflets étant fermés chacun par un fond mobile et étant fixés au boîtier à leur autre extrémité, et un organe actionneur, soumis en permanence à la pression d'un ressort, accouplé rigidement ou élastiquement aux fonds des soufflets. Le boîtier 1 comporte une paroi périphérique 8 entourant le soufflet supplémentaire 4 et une paroi d'extrémité 9, parallèle aux fonds 3, 5 des soufflets 2, 4 et munie d'une ouverture 23 pour le passage de l'organe actionneur 18, et le soufflet supplémentaire est suffisamment souple pour qu'il s'applique contre la paroi latérale et contre la paroi d'extrémité en cas de surpression à l'intérieur de l'espace de surveillance 15. Application aux installations de chaudières de chauffage à vapeur ou aux installations frigorifiques.
