Abstract
Una valvola, in particolare per erogatori di autorespiratori subacquei comprende un otturatore tubolare (9) che è alloggiato in modo assialmente scorrevole in due adiacenti camere (6, 7) e le separa tra loro a tenuta, di cui una camera (6), detta di pressione, essendo comunicante con una sorgente di gas sotto pressione e provvista di una sede (11) cooperante con la relativa estremità (109) dell'otturatore tubolare (9), e l'altra detta di compensazione (7) è provvista di aperture (107) di comunicazione con l'esterno, mentre in essa è guidata a tenuta la corrispondente estremità dell'otturatore tubolare (9) a guisa di testa allargata d'espansione (209) che comunica con l'uscita (12) della valvola, essendo una molla elicoidale (10) interposta tra la testa d'espansione (209) e l'opposta parete divisoria (8) tra le dette due camere. Per evitare lo scambio termico tra la camera di compensazione e l'otturatore (9) soggetto al raffreddamento a causa dell'espansione del gas nella testa d'espansione (209), il trovato prevede un elemento d'isolamento termico (13) interposto almeno tra la molla elicoidale (10) e la testa d'espansione (209).
