Airstream Propelled Spray Atomizer Apparatus and Method of Fluid Atomization by Codirectional Airstream Propulsion

An airstream propelled spray atomizer apparatus comprising:

• a handheld nozzle having;
• an elongate barrel having an aperture;
• a catheter disposed interior to the barrel;
• a terminus disposed endwise upon the catheter;
• a handle member;
• a trigger member disposed in operational communication with an air trigger valve whereby depression of the trigger member opens the air trigger valve and restoration of the trigger member closes the air trigger valve;
• a fluid supply line disposed in operational communication with a fluid drawback valve and a fluid metering valve, said fluid supply line operatively couplable with a reservoir;
• an airflow supply line disposed in operational communication with a spray air valve, said airflow supply line operatively couplable with a compressor;
• an airstream supply line operatively coupling the barrel to the airflow supply line downstream of the spray air valve;
• and
• a control signal line branched off of the airflow supply line to route a control signal to pressurize and open the fluid drawback valve and the spray air valve, said control signal line operationally coupled with the air trigger valve;
• wherein a first fluid is forcible from the compressor as an airstream into the barrel and out the aperture and a second fluid is introducible into the airstream for atomization therein.

A method of atomizing a fluid by codirectional airstream propulsion comprising the steps of:

• accelerating a first fluid along an elongate barrel towards an aperture;
• and
• introducing a second fluid into the accelerated first fluid from a terminus coaxially disposed interior to the barrel, said terminus spaced back from the aperture to define a mixing zone;
• wherein the second fluid is atomized by introduction into the first fluid for ejection from the aperture as an atomized mist.
