Abstract: An improved construction for a hand operated electrostatic spray coating device of the so-called airless type in which atomization is effected by the interaction of a high speed fluid stream with air, including a self-contained electrogasdynamic generator as a power source for charging the spray and maintaining an electrostatic depositing field and a pneumatically assisted fluid valve mechanism operatively responsive to at least a portion of the air flowing through the electrogasdynamic generator.

Abstract: Improved methods and apparatus for charging atomized coating materials and maintaining an electrostatic depositing field in the electrostatic deposition of coating materials. Improved charging is effected by the selectively directed passage of corona discharge current from a primary source thereof through emitted coating material intermediate its point of emission and its locus of atomization to an electrically floating electrode element whose collection potential is maintained by a corona discharge emanating from an exposed end thereof.
