  • Method and means for producing and dispensing extinguishing fluids
    Patent number: 4645009
    Abstract: The invention relates to a method and a device for producing and dispensing extinguishing fluids mixed with adjuvants. The adjuvants are drawn in by suction in a metered manner and fed to a suction or intake pipe of an extinguishing fluid pump. A partial volume of the extinguishing fluid proportional to the quantity of extinguishing fluid conveyed in the delivery pipe is withdrawn from the delivery pipe. A negative pressure is generated thereby, by means of which the adjuvant is drawn in by suction and mixed with the extinguishing fluid. The extinguishing fluid mixed with additive is then fed to the suction or intake pipe of the extinguishing fluid pump.
