Abstract

Costituisce l'oggetto del presente modello di utilità un nuovo tipo di valvola di sicurezza per gas e fluidi gassosi, come specificato nel titolo, realizzata mediante l'adozione d'un elemento fusibile e una nuova guarnizione di tenuta con la bombola, che risultano capaci di realizzare la tenuta degli elementi quando eventuali sbalzi termici, a cui essa può essere soggetta, intervengono a rendere critica la tenuta del gas fuoriuscente dalla bombola stessa.
