Deflectors are made in the form of bowls oriented toward inlet opening. Converging openings are provided forward of each of said deflectors, with converging opening of larger diameter being positioned near inner cavity of casing. Lower generatrix of converging openings is extending in horizontal plane. Converging openings on side surface are arranged in helical line. Flow dividers are provided within inner cavity of casing, at the level of horizontal generatrices of converging openings, with width of flow dividers increasing from inlet opening to outlet opening along conical generatrix. There are flow guides between flow dividers, in particular, between converging openings. Flow divider bottoms are joined to upper edges of converging openings. Distance between deflectors is selected on condition that converging openings and flanges for fastening of deflectors should be received therebetween.

EFFECT: increased efficiency in selection of optimal irrigation parameters and enhanced reliability in operation of sprinkler head.
