ABSTRACT:
The nozzle effects three stages of liquid atomization. The first stage is carried out by means of a single liquid orifice and an expansion chamber containing an impingement pin. A high velocity stream of liquid is discharged through the liquid orifice and is broken-up upon striking the flat end of the impingement pin. The second stage is produced by an air guide which reduces in area to form jets of air into a high velocity annular air curtain, the curtain passing through the liquid orifice in surrounding relation with the liquid stream and striking the broken-up flow of the first stage to atomize the particles. The mixture is then allowed to expand in the expansion chamber to reduce the tendency of the liquid particles in the atomized mixture from commingling together and reforming into larger particles. The third stage is effected by the expansion chamber and by multiple discharge orifices. The mixture is sprayed from the expansion chamber through the multiple orifices and, upon being discharged into the atmosphere, the particles are atomized further due to the release of pressure formed inside the expansion chamber.
