ABSTRACT:
Improved device for dispersing into the atmosphere exhaust gases in the form of mixtures having a controlled composition. The device, consisting of a mixing duct provided with an axial injector extending from a supply tube for gas under high pressure, the ratio of the square roots of the areas of the sections of the duct and the injector lying between 30 and 300, is characterized in that it comprises, positioned on the supply tube of the injector, a control mechanism delivering to the injector a flow of gas under a pressure intermediate between the high initial supply pressure and the pressure prevailing in the mixing duct, the control mechanism being provided with means for fixing the maximum value of the pressure at which the gas is delivered to the injector. This improvement in devices for dispersing exhaust gases renders them more efficient when they are used to purge or evacuate the chamber which is not being supplied.
