FIELD: machine building; construction.SUBSTANCE: fluid sprayer comprises housing, tubular insert and passive fluid feed pipe. Housing has series-arranged, on path of gaseous medium, cylindrical section, confuser and diffuser. Tubular insert is fitted inside housing along its axis, has axial channel for feeding active gaseous medium and an axial active nozzle at its end. Outer surface of tubular insert and housing inner surface form on path of gaseous medium an annular channel to feed active gaseous medium, an annular active nozzle, an annular passive nozzle and a receiving chamber. Annular active nozzle has a confuser and is equipped with curved radial partitions. Axial active nozzle has a confuser and is shifted relative to annular active nozzle in axial direction towards diffuser. There are through-holes in diffuser walls. Diffuser is equipped with a sealed outer jacket. Cavity between diffuser and housing is connected by at least one hollow tube with receiving chamber. In cavity of diffuser there is a reflector in form of a right circular cone, rotation axis of which coincides with axis of rotation of diffuser, and top faces housing of confuser.EFFECT: invention can be used for application of liquids and oil on solid surfaces.3 cl, 3 dwg |
