ABSTRACT Fire extinguishing devices are designed to extinguish specific classes of fires. The action and character of the fire extin- guishing stream are planned and fixed to combat a specific fire in a fixed state of burning. The invention, a venturi-activated tube, extinguishes fire in it's changing states of burning, in it's stages of development and composition. The ejector-tube can discharge fire extin- guishing agents at sonic velocities to counterbalance suction flows extinguishing fire in- and through the hollow center ax s of the tube. The heat of the damaging fire regulates the optimum densities of the unified discharge- and suction flows. Pressure and suction forces combine to increase the power of this invention to put out fire. The ejector is self-adjusting and self-cleaning. The orifice Abstract ring opens under overthrust created by driving pressures to dis- charge flow-obstructing solids automatically.
