Abstract
Disclosed is a valve assembly and process for dispensing gas from a storage vessel that comprises a nozzle for discharging the gas. The valve assembly has a passage having a first end is in communication with the nozzle, and a second end in communication with an interior of the storage vessel where the gas is stored. A shut off valve is interposed in the passage for blocking or allowing gas to pass between said first end and the second end of the passage. A check valve may be secured in a bore of the nozzle to prevent accidental gas discharge.

A valve assembly for dispensing gas from a storage vessel, comprising:
- a nozzle for dispensing gas from the storage vessel;
- a passage having a first end in communication with said nozzle and a second end in communication with an interior volume of the storage vessel;
- a shut off valve interposed in said passage for blocking or allowing gas to pass between said first end and said second end of said passage;
- and
- a check valve secured in said nozzle.
A process for dispensing gas from a storage vessel, comprising:
- biasing an obstruction in a chamber into engagement with a channel in a nozzle to prevent passage of fluid from said channel to said chamber;
- communicating an interior volume of said storage vessel with said nozzle,
- reducing pressure in the chamber to below the pressure in the channel sufficiently to move the obstruction out of engagement with the channel to permit passage of fluid from said channel to said chamber.
A valve assembly for dispensing gas from a storage vessel, comprising:
- a nozzle for dispensing gas from the storage vessel, said nozzle defining a bore;
- a passage having a first end in communication with said nozzle and a second end in communication with an interior volume of the storage vessel;
- a shut off valve interposed in said passage for blocking or allowing gas to pass between said first end and said second end of said passage;
- and
- a check valve secured in said bore, said check valve comprising an outer body defining a channel in communication with said passage and a chamber in communication with said channel, said chamber including a movable obstruction that can move into engagement with said channel to prevent fluid flow through said check valve and out of engagement with said channel to allow fluid flow through said check valve.
