Abstract

L'addition concerne un mode de réalisation du diaphragme du robinet du brevet principaL Le diaphragme 31 comporte un empilage de lames métalliques flexibles 63, 55 disposé entre la tige de manoeuvre du robinet et l'obturateur pour assurer leur séparation étanche. Les lames sont toutes fabriquées dans le meme alliage mais les lames extérieures 63 sont plus épaisses que les lames intérieures 65. L'empilage est fixé sur son bord au corps 10 du robinet par un assemblage comportant une partie extérieure de serrage suivie d'une partie de retenue assurant une maîtrise prédéterminée du flambage Application aux robinets.
