Abstract

Dispositif de protection pour manomètre différentiel. Une enceinte est séparée par une paroi mobile 10 en deux compartiments reliés chacun à une des entrées du manomètre 1. Chaque chambre est munie d'un clapet de décharge 16 ou 22 coopérant avec la paroi mobile de façon à être ouvert par cette dernière lorsque la différence de pression qui s'exerce sur la paroi mobile dépasse une valeur déterminée p. Applications courantes.
