Abstract
In accordance with the present invention, there is provided a balanced high volume, low pressure paint spray gun. The spray gun is provided with a spray gun body connectable to a paint source and an air source. The spray gun is provided with a head insert engaged with the spray gun body. The head insert has a paint atomization chamber formed therein, a paint passage formed therethrough extending into the paint atomization chamber for receiving paint from the paint source, an atomization air passage and a shaping air passage for receiving air flow from the air source therethrough, and a balancing air passage formed therein extending into the paint atomization chamber. The spray gun further has a shaping air chamber defined by the spray gun body. The shaping air chamber is disposed in fluid communication with the air source for receiving air flow therein, disposed in fluid communication with the shaping air passage for shaping spray patterns of atomized paint, and disposed in fluid communication with the balancing air passage. The paint atomization chamber defines a paint atomization zone, a paint spray pattern shaping zone, and an air pressure zone. The paint atomization zone is in fluid communication with the paint passage and the atomization air passage for discharging atomized paint therefrom. The paint spray pattern shaping zone is in fluid communication with the shaping air passage for shaping spray patterns of atomized paint. The air pressure zone is in fluid communication with the balancing air passage for regulating air pressure between the paint atomization chamber and the shaping air chamber.
