FIELD: technological processes.
SUBSTANCE: invention is related to irrigation equipment and may be used in water sprinkler machines. Invention objective is to increase quality of artificial rain. For this purpose body flow path is arranged with abrupt narrowing. Hole that compresses jet is arranged in the form of cylindrical nozzle with sharp inlet edge and cylindrical part with length of at least four diametres of jet (d) with radial holes 0.2 d at the distance of 0.5 d from sharp edge. Deflector is arranged as flat, with diametre of (2.5-3)d with triangular grooves on deflector working surface. Grooves are located in the form of fan with wrapping angle of 180° with fan centre displaced to the side of pressing hole. Check-nut serves for fixation of nozzle in required area.
EFFECT: lower rain intensity, smaller drop size and lower energy of soil impact, higher wind resistance.
