Abstract
An electrostatic spray coating apparatus is disclosed which comprises a spray nozzle containing both air and liquid discharge ports, an inductive charging device or charging electrode located exteriorly of the discharge ports and attached to the spray nozzle, and electrical connections for applying an electric potential to the inductive charging device. The inductive charging device or charging electrode creates a charging zone, and is preferably positioned so that ambient air is mixed with air and fluid exiting from the discharge ports within the charging zone.
