Definitions
- the invention relates more particularly to devices of the needle valve type, the metallic body of which comprises, between an inlet channel for the gas flow to be controlled and an outlet channel for the controlled gas stream, an intermediate chamber provided coaxially with a seat for a needle, with a threaded bore opening to the outside and serving, by screwing, for mounting the needle, generally provided with a control wheel. It is also known to regulate the pressure of a gas flow by means of a regulator taking into account the external or ambient pressure and the variations in pressure of the gas source.
