<p>This invention concerns a high rate discharge valve for high pressure gas cylinder provided with connections for refilling and discharging gas. A valv e body (2) presents an internal duct (3a) and a central hole (8), connected to a cylindrical chamber (10), in which a piston (12) is housed. The piston is attached to a valve actuator (142) which is urged against a seat by a spring (15). Connected to the body (2) are a gas supply duct, a refill valve, a val ve opening actuator duct (17), a duct (18) connecting the opening actuator duct with the piston operating area (18a), a nipple (6) for a pressure switch (19 ) and a pressure gauge.</p> |
