Abstract

Il s'agit d'une valve à commande thermique dans laquelle il y a, conditionée par la force d'ouverture d'un ressort, pour la fermeture de la valve, une force de fermeture relativement grande à transmettre d'un organe en forme de membrane à une partie obturatrice. Dans l'organe en forme de membrane apparaissent de ce fait de grandes tensions influençant défavorablement la longévité de la membrane. La nouvelle valve doit présenter une très grande longévité de la membrane. Le ressort est réalisé en ressort à plateau (14) et il appuie l'organe en forme de membrane (7), pendant toute sa course, sur une grande surface, à l'encontre de la pression intérieure de la capsule à membrane (5). La nouvelle valve avec capsule à membrane s'applique à de grands domaines de pressions d'utilisation.
