ABSTRACT:
An electrostatic powder spray gun is provided with an arcuate nozzle tube forming a curved passage between an inlet and outlet orifice. A mixture of powder particles and a carrier gas injected into the inlet orifice is subjected to a swirling motion prior to exiting the outlet orifice. This swirling motion is caused by helical grooves cut into the inside surface of the arcuate tube adjacent to the outlet orifice. An electrode imparts an electrical charge to the particles as they exit from the nozzle tube.
