Abstract

L'invenzione concerne una valvola di insufflazione di gas per iniettare combustibile gassoso nella camera di combustione di un motore a combustione interna, con uno stantuffo condotto in modo da spostarsi longitudinalmente nell'involucro della valvola e con una valvola a tazza collegata con detto stantuffo, prevista per il controllo di un foro di scarico e atta ad aprirsi in direzione di flusso del gas, inoltre con una camera di lavoro idraulica di comando caricabile dalla pressione di alimentazione del liquido idraulico di comando alimentato da una pompa premente, la quale camera è separata dalla camera del gas mediante uno stantuffo, dove la valvola a tazza, in presenza di camera di lavoro idraulica di comando decompressa, é fissabile in posizione di chiusura esclusivamente tramite la pressione del gas.
