<p>The assembly includes a body in which there is formed a bore (3) for letting in gas under pressure, containing an isolation valve (4) exposed to the gas under pressure, at least one pressure reducer (5), means (9) for selecting and regulating the flow rate through at least one outlet (8) for gas at reduced pressure, and a tubular member (11) for controlling the isolation valve sitting on top of the body, the isolation valve being a spool (4) which can be moved back and forth in a transverse housing (26) in the body and the opposite ends of which interact directly with curved guide ramps (18, 19) formed by the tubular control member. The direct control of the isolation spool (4) by turning the tubular member (11) simplifies the architecture of the assembly and reduces the manufacturing and servicing costs thereof. Application to transportable bottles of gas, especially of medical oxygen.</p> |
