Valve for high pressure fluid container.

摘要

A valve having a valve housing for mounting on a high pressure fluid container. A cartridge is mounted in a fluid conduit in the valve housing leading to the fluid container. A metallic disc is crushed by the cartridge against a valve seat in the conduit to provide a reliable lasting seal. Opening of the valve is provided by releasing a trigger pin connected to a latch in the cartridge for removing a support from a portion of the disc permitting it to rupture under the high pressure and communicating the high pressure gas to a pressure regulator chamber in cross configuration with the valve conduit in the valve housing. A pressure regulator member in the chamber controls the size of a discharge orifice for lowering the pressure and introducing the gas into an inflatable body. Filling of the high pressure fluid container may be done by introducing high pressure fluid into the regulator for passage into the fluid conduit of the valve with the cartridge carrying the disc spaced from the valve seat. After the container is filled the cartridge including the disc support moves the disc into sealing engagement with the valve seat.
