Abstract

Valvola combinata di regolazione in cui la tenuta verso l'esterno è conseguita con una doppia baderna intervallata da una lanterna con sfiato intermedio, la quale viene pressata assialmente tra lo stelo e la guida dell'otturatore principale da elementi elastici precaricati, mentre la detta guida è tenuta elasticamente pressata contro la superficie diversamente inclinata di un anello di spallamento trattenuto da settori circolari incastrati nel corpo valvola, in cui tra la detta guida ed il detto otturatore principale è interposta una serie di labirinti, in cui l'otturatore pilota è a profilo parabolico e tra la prima sede ed il corpo valvola è situato un elemento elastico di tenuta a soffietto ed in cui il trio è costituito da una struttura cilindrica cava inserita coassialmente in una cavità di testa dell'otturatore principale, che, provvista di fori trasversali disposti sfalsati rispetto a corrispondenti fori della cavità, termina con un profilo parabolico.
