摘要： An instant-on valve assembly with manual override is designed to be connected to a tank containing high pressure gaseous fuel. The valve assembly and manual override allows the tank to be alternately closed off, vented or allows the gas in the tank to bypass the instant-on valve. The instant-on valve assembly can be repaired or replaced without venting the tank. The instant-on valve assembly has a main valve and a bleed valve The main valve has a secondary plunger that opens and closes a main orifice. The bleed valve has a bleed valve stem that opens and closes a bleed orifice. The main valve is slidably mounted within a housing and has a chamber at one end and a zone at another end. Both the zone and the chamber have access to high pressure gaseous fuel within the tank. High pressure gaseous fluid within the zone can be drained when the bleed valve stem is fully open. The bleed valve stem is connected to a solenoid and opens upon activation of the solenoid. When the pressure within the zone is sufficiently reduced, the pressure within the chamber will cause the main valve to open by sliding into the zone. A spring moves the main valve towards a closed position when the solenoid is deactivated. Since the volume of the zone is relatively small, the main valve opens within one second after the solenoid is activated.
