During insertion of the cartridge 14 into the cavity 8.2, the securing ring 20 is radially compressed so as to pass the outer edge 8.1 and contact the inner face of the distal cylindrical wall 8. The flow selector can then be inserted further into the cavity 8.2 while the central portion

  • the pressure reducer 26 comprises also a compression spring 26.4, for instance two coaxial springs, abutting at one end against the piston
  • a regulating chamber 28 is delimited by the piston 26.1 , the cartridge 14 of the flow selector 12 and by a proximal portion 8.5 of the distal cylindrical wall 8.

  • the cartridge 14 of the flow selector 12 comprises essentially a body 14.1 with a gasket (not represented) in the annular housing 14.2, for cooperating with the inner face of the distal cavity formed by the distal cylindrical wall 8.

  • the gas under pressure flows through the seat 26.3, along the sealing element 26.2 and through the shaft of the piston 26.1 of the pressure reducer 26 so as to reach the regulating chamber 28.
  • the pressure in that chamber urges the piston 26.1 and the sealing element 26.2 towards the seat 26.3 so as to substantially reduce the cross-section of the passage through said seat, thereby reducing in a substantial manner the pressure.
  • the gas under a reduced pressure in the regulating chamber 28 flows out to the gas outlet fitting 18 through the calibrated hole that is placed in front of the exit passage 30 (figure 3).
  • the construction of the above described gas flow device is particularly interesting in that its assembly is substantially simplified and rendered cheaper. Indeed, the cavity 6.3 of the main portion 6 of the body 4 can be easily machined along the longitudinal axis. Also the attached distal cylindrical wall 8 does not need to be mounted in a gas tight fashion to the main portion 6 in view of the fact that the proximal cavity 6.3 is vented to the atmosphere. Similarly, the distal cylindrical wall 8 is a revolution piece, i.e. can be machined on a lathe with exception of the radial bores receiving the fastening screws 10. The mounting of the flow selector is also quite simple as detailed above in relation with figure 1.
