Abstract
The gas control and dispensing assembly comprises a lower block (1) , mounted on a gas bottle (4) and comprising a manometer (9) and a filling connector (11), and on which a subassembly (32, 17 ) is permanently mounted, axially movable in response to a rotation of a tubular control and actuation member (46) surrounding the subassembly, which contains a pressure reducer (27) and an indexable flow regulator (34, 35) and has a low-pressure outlet (45) and a medium-pressure outlet (51). Application in particular to dispensing medical oxygen.
Claims18
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.
Gas control and dispensing assembly for connection to a tank containing 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 couplable to said shut-off valve, and a flow regulator, said flow regulator and said pressure reducer means being assembled in a first mobile subassembly which includes a second gas outlet upstream of said flow regulator, and first mobile subassembly being arranged in a control add actuation structure solidly attached to a second subassembly which incorporates said shut-off valve.
Gas control dispensing assembly for connection to a tank containing gas under high pressure, comprising a first gas outlet, a shutoff valve connected in series between the tank and the first gas outlet and being exposed to said high pressure, pressure reducer means couplable to said shut-off valve, 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 solidly attached to a second subassembly which incorporates said shut-off valve, and wherein said pressure reducer means is arranged in a first block slidingly interacting with a first end of said second subassembly and comprising a hollow rod portion selectively interacting with said shut-off valve.
A gas bottle containing gas under a high pressure and equipped with a gas control and dispensing assembly connected thereto and having a first gas outlet, a shut-off valve connected in series between the bottle and the first gas outlet, pressure reducer means couplable to said shut-off valve, a flow regulator, said first gas outlet, said flow regulator and said pressure reducer means being assembled in a first mobile subassembly arranged in a control and actuation structure solidly attached to a second subassembly which incorporates said shut-off valve, said first mobile subassembly including a second gas outlet upstream of said flow regulator and said second subassembly comprising a tubular block having a second end provided with means for mounting on said gas bottle.
