An integrated valve assembly and apparatus. The assembly has a main body that includes (1) an internal gas passage for conveying gas between a gas inlet and a gas outlet; (2) a gas expansion means placed in the internal gas passage between the gas inlet and the gas outlet; (3) and a locking valve that is used for controlling the release of the gas. Also included is a rotary actuator that can be operated by the user. This rotary actuator includes a blocking means that acts on the rotary actuator to prevent rotation of the rotary actuator. The integrated valve assembly may be used in a portable equipment unit that includes a compressed-oxygen bottle on which the valve assembly is mounted, and may optionally include a protective shroud for protecting the assembly and a demand valve connected to oxygen therapy nose clips, to a flowmeter or to any other similar device.

The invention claimed is: 1. An integrated valve assembly with a main body comprising: a) an internal gas passage for conveying gas between a gas inlet and a gas outlet; b) a gas expansion means placed in said internal gas passage between said gas inlet and said gas outlet; and c) a locking valve used for controlling the release of the gas and comprising a rotary actuator that can be operated by the user, wherein said locking valve further comprises a blocking means that acts on the rotary actuator of the locking valve to prevent the rotation of said rotary actuator, said rotary actuator being centered on a boss of said valve assembly, wherein said boss supports said gas outlet and a connection means for connecting a gas use device provided with an inlet interface and with additional connection means capable of cooperating with the connection means and with said blocking means so as to permit said rotary actuator to rotate after said inlet interface has been connected to an outlet interface of the valve assembly. 2. The assembly of claim 1, wherein said blocking means further comprises one or more moving parts that cooperate with said rotary actuator to prevent its rotation and the release of the gas. 3. The assembly of claim 2, wherein said at least one moving part is pushed back by one or more spring means towards said rotary actuator so as to be at least partially housed in at least one recess provided in said rotary actuator and designed to accommodate at least one portion of said moving part, so as to prevent the rotation of said rotary actuator when said moving part is at least partially housed in said recess. 4. The assembly of claim 1, wherein said rotary actuator is a rotary ring. 5. The assembly of claim 3, wherein said one or more spring means are springs. 6. The assembly of claim 3, said one or more moving parts are selected from the group consisting of pins and balls. 7. The assembly of claim 1, wherein said gas expansion means comprises a first expansion stage and a second expansion stage that are placed in said internal gas passage, wherein said second expansion stage is located downstream of said first expansion stage. 8. The assembly of claim 7, further comprising: a) a residual pressure valve; b) a pressure gauge for displaying a pressure available in a bottle connected to the assembly; c) a filling connector; d) a filter; and e) a safety valve for discharging any possible overpressure in the event of failure or rupture of the first expansion valve element of the first expansion stage. 9. The assembly of claim 7, further comprising an instant action means, actuatable by an operator, which acts on said expansion means of said second expansion stage so as to instantly increase the released pressure and the flow rate of gas delivered, during the time that said means is being actuated by the operator. 10. The assembly of claim 9, wherein said instant action means is a button that compresses a piston release spring of said second expansion stage. 11. An apparatus which is portable and ambulatory, comprising a compressed-gas bottle onto which is fitted an integrated valve assembly according to claim 1, wherein said apparatus weighs less than 2 kg. 12. The apparatus of claim 11, wherein said compressed-gas bottle contains oxygen. 13. An apparatus comprising a compressed-gas bottle onto which is fitted an integrated valve assembly according to claim 1, wherein said apparatus weighs less than 2 kg. 14. The apparatus of claim 13, further comprising a gas use device connected, via an inlet interface, to said outlet interface, said gas use device comprising complementary connection means that cooperate with said connection means of said outlet interface of the valve assembly and with a locking means that acts on said rotary actuator so as to permit said rotary actuator to rotate and gas to flow from said valve assembly to said gas use device. 15. The apparatus of claim 14, wherein said gas use device is chosen from the group consisting of demand valves and flowmeters. 16. The apparatus of claim 11, wherein a protective shroud is placed so as to protect said integrated valve assembly. 17. The apparatus of claim 16, wherein said protective shroud is fastened to said valve assembly.
