Gas dispensing control assembly and gas bottle equipped with such an assembly
First Claim
1. Gas control and dispensing assembly for connection to a tank containing said gas under high pressure, comprising a first gas outlet, a shut-off valve connected in series between the tank and the first gas outlet and being exposed to said high pressure, pressure reducer means coupled to said shut-off valve for reducing the pressure of gas flowing to said first gas outlet, and a flow regulator, said flow regulator and said pressure reducer means being assembled in a first mobile subassembly arranged in a control and actuation structure securedly attached but moveable with respect to a second subassembly which incorporates said shut-off valve.
