FIELD: hygiene.SUBSTANCE: invention relates to devices for cleaning surfaces and can be used as nozzle for installation of water-jet treatment of surfaces. Localizing nozzle comprises dome-shaped case, annular cavity inside case, formed by space between outer and inner walls of case, fluid supply system, air flow pressure source, fluid suction system. Fluid suction system comprises discharge pipe and rarefaction source. Circular cavity is connected with air flow pressure source through air supply branch pipe, placed on outer surface of case.EFFECT: technical result is exclusion of ingress of sprayed liquid drops beyond nozzle case circuit due to air flow, organized in circumferential direction between nozzle end of localizing and cleaned surface, decrease of dependence of efficiency of drops localizing (limitation of spraying) of height of end gap between nozzle and cleaned surface, achievement of required localization efficiency at treatment of surfaces with greater curvature or with large roughness.1 cl, 2 dwg |
