Fire extinguishing devices are designed to extinguish specific classes of fires. Fire extinguishing streams are being planned and being fixed to combat a kind of fire in a fixed state of burning. The invention, a venturi activated tube extinguishes fire in its changing states of burning, in its stages of development and composition. The ejector tube is designed to discharge extinguishing streams with sonic velocities continuously counterbalanced by suction flows at sonic speed along the center axis of the hollow tube. The heat of the damaging fire regulates the densities of the unified discharge and suction flows. Combined forces of pressure and suction increase the capacity of this invention to combat fire. The ejector tube is self-adjusting and self-cleaning. The ring orifice reacts under overthrust pressures to discharge flow obstructing solids automatically.
