Abstract

Clapet obturateur à plusieurs papillons pour installations de transport d'air. Pour éviter la formation d'une fente assez grande entre les papillons 3 dans le cas où ceux-ci viendraient à gauchir, l'une des deux arêtes de chaque papillon est conçue de façon à former une contre-face 8 étroite et sensiblement perpendiculaire au plan du papillon, située en regard de l'arête 4 du papillon adjacent. Application : clapet à papillons multiples installé dans une conduite de transport d'air.
