The invention relates to fire and agricultural machinery can be used for fire control and spraying plants. The technical problem is to simplify the construction, expansion opportunities.; The apparatus comprises a knapsack tank connected by a hose to a hand pump 3 having a hollow stem 4 for supplying the liquid. The rod 4 is connected with a sprinkler 5. The sprinkler comprises a core 6 with a tapered tip 7. In the core are radial holes "b" for communicating with the cavity of the nozzle 8. The tip 7 grooves "a" communicated with the nozzle 9. The inner cavity of the nozzle has a tapered portion "g", corresponding to a cone on the tip of the nozzle 7. The cavity communicates through the groove "b" with the nozzle 9. The nozzle is connected to the core by a screw 10. to seal has a rubber ring 11. The liquid spray mode depends on the size of the gap between the plug 7 and the portion "d" of the orifice. This parameter is adjusted by screwing the nozzle from the mandrel.; 2 is the n-p-ly, 3 Fig.
