SPHERICAL OR ELLIPTICAL DUAL STRUCTURED PRESSURIZING/ATOMIZING NOZZLE

PROBLEM TO BE SOLVED: To obtain a new spraying nozzle of simple shape, lightweight, and low cost, which neither clogs nor blocks, has long service life of secular deterioration, and enebles the configuration of a number of products from the same shape of the nozzle. SOLUTION: Liquid passes through an introducing inlet 2 mounted to turn in the tangential direction of a spherical or elliptical nozzle 1, enters the spherical or elliptical nozzle while turning therein, and is sprayed from jets 3 beforehand bored at almost right angles with the inlet 2. The nozzle is a spraying nozzle of single fluid if one inlet 2 is provided, and is a mixing nozzle of a plurality of fluids if a plurality of the inlets 2 are provided. It is desirable that the jets 3 are in principle at the positions of right angle. However, sticking to the right angle is not inevitably required, arbitrary positions may be acceptable, and one jet 3 or a plurality of them may be provided. The structure of dual structured pressurizing/atomizing nozzle comprising a compressed air introducing inlet of sphere or ellipse for liquid or a spherical or elliptical compressed air introducing inlet on the rind of a cylindrical/conical nozzle, and having compressed air jets 4 by a pressurized gas guide ring comprising gaps of 1 to several millimeters on the circumference of the spraying outlets in a liquid nozzle, is provided.
