FIELD: devices for spraying liquids.SUBSTANCE: invention relates to spraying of liquids. Atomizer comprises housing, union and a coaxially positioned swirling insert with an external helical thread and an expanding conical opening inside. In the fitting a cylindrical inlet opening is made, connected to the diffuser, which is made axially symmetric in the housing. In the lower part of the body there is an atomizer which is arranged axisymmetrically to the body and is two-stage and coaxial to the swirling insert. First stage of the atomizer is a mixing chamber, which is made in the form of a confuser, in series connected to an expanding conical hole made inside the swirling insert. Second stage of the atomizer is a continuation of its first stage, made in the form of a diffuser, while the internal conical surface of the diffuser is screw-threaded.EFFECT: invention makes it possible to improve the liquid spraying quality, productivity of the atomizer, and to reduce hydraulic losses.4 cl, 1 dwg
