Abstract
A gas assisted liquid spray nozzle assembly having a nozzle body that defines a mixing zone, a liquid inlet communicating with the mixing zone from an end, and a pressurized gas inlet communicating with the mixing chamber from an upstream side. The liquid inlet includes a liquid injector extending into the nozzle body having a liquid inlet extension passage and a plurality of discharge orifices adjacent a closed downstream end which define an impingement surface for directing liquid into the mixing zone in transverse relation to a central axis of the mixing zone. The nozzle body and liquid injector define a plurality of concentrating gas discharge passages at respective locations of the injector liquid discharge orifices for causing individual pressurized gas to directly interact with transversely directed liquid into the mixing zone for enhanced atomization and ultimate discharge from a downstream spray tip.
