Abstract

Contenitore a pressione per l'accumulo di un gas con una valvola di scarico collegata, in corrispondenza di una zona di rottura nominale, con l'involucro del contenitore a pressione che contiene un pistone che si estende verso un sistema pirotecnico disposto nell'interno del contenitore.Nello stato della tecnica, la caratteristica di fuoriuscita di un gas che da un contenitore a pressione scorre in un cuscino a gas non è influenzabile in modo programmato durante il movimento di apertura della valvola di scarico.Secondo l'invenzione, una tale influenza è possibile, la valvola di scarico contenendo un corpo di comando attiguo alla zona di rottura nominale, che si estende in direzione del sistema pirotecnico, la cui sezione trasversale cambia in direzione assiale della valvola di scarico.Impiego nei sistemi di protezione a cuscino a gas per i passeggeri durante il trasporto di persone.Fig. 1.
