Deflector of proposed sprinkler activator is arranged ahead of the casing orifices. Orifice top edge mates the deflector rounded lower part. Deflector top edge seats above that of the water outlet to mate with deflector lower edge. Conical water spreader seats inside the casing to mate with water outlet orifice rounded lower edge. Conical water spreader side surface accommodates L.H.-thread auger-type guide. Auger thread OD equals the casing ID. Starts of auger thread equal the number of water outlet orifices. The number and diametre of water outlet orifices are selected to allow preset sprinkling flow rate. Water outlet orifice inside accommodate L.H.-thread helical guides. Water outlet orifices are made in the casing along tangential line to casing ID, and inclined to horizontal plane.

EFFECT: possibility to select optimum parametres of sprinkling, higher reliability, simpler design.
