Abstract
The invention relates to a nozzle () for mixing a gaseous fluid such as air and a liquid such as water and for ejecting an atomized mist of liquid droplets. The nozzle includes a nozzle body defining first (), second () and third () annular passages along the length thereof. Pressurized fluid is introduced into the first annular passage () and a first restricted annular orifice () leads from the first annular passage () to the third annular passage (). Liquid is introduced into the second annular passage () and a second restricted annular orifice () leads from the second annular passage () to the third annular passage (). Liquid and gaseous fluid are aggressively mixed in the third annular passage (). A third restricted annular orifice () leads from the third annular passage () to atmosphere such that mixed liquid and gaseous fluid are forcibly ejected from the nozzle through the third restricted annular orifice (), the liquid being atomized in small controlled droplets in the ejected gaseous fluid.
