The atomizer includes a pair of complemental sections held together so that at least one is rotatable relative to the other; the complemental meeting edges are helical, the beginning of each helix forming a shoulder, whereby the rotating of one of the sections relative to the other determines a slit of selected length for the nozzle orifice; the sections herein illustrated are half-spheres which are sufficiently hollow to form a chamber at the meeting edges; means being provided to introduce a medium under low pressure to be expelled through the nozzle orifice; and axial means being provided to adjustably hold the two elements; in the present illustration a low pressure gaseous substance, such as air is expelled through the nozzle orifice to atomize a liquid which is introduced so as to spread over the aforesaid spherical surface and over said orifice; one or more such coacting shoulders may be provided on the helical meeting edges to provide one or more nozzle orifices adjustable simultaneously.
