FIELD: fire-fighting equipment, particularly to exert influence of sprayed fire-extinguishing liquid on fire site, to obtain finely-dispersed liquid for disinfection, degassing, decontamination, fertilizer application, watering and so on.
SUBSTANCE: device has barrel with inlet orifice, fire-extinguishing liquid tank, connection pipe to connect the tank with inlet orifice, gas pulse generator joined to the barrel, means to supply compressed gas to the device and triggering mechanism. Barrel center has smooth elbow area, which retains liquid inside the barrel below outlet orifice thereof. Fire-extinguishing liquid tank and barrel are made as communicated vessels. Inlet orifice is provided with check valve. The elbow barrel area may be shaped as 
.
EFFECT: prevention of fire-extinguishing liquid leakage from barrel of fire-fighting apparatus, increased distance of fire-extinguishing liquid throw.
