Abstract
A spray gun suitable for electrostatic coating, using a coating material whose electric resistance is relatively low. A coating material nozzle is attached to the front middle region of a barrel having a forwardly projecting cylindrical section on the front outer peripheral edge, and an air cap which covers their front surfaces is installed. A pattern air flow channel is formed between the air cap, coating material nozzle outer peripheral surface and the cylindrical section inner peripheral surface, and an annular electrode is attached to the inside of the flow channel. The air cap is centrally provided with an atomization air spout hole, and a coating material delivery port at the front end of the coating material nozzle is inserted therein. A pin electrode is projected forward through the coating material delivery port. Two pairs of projections project forward from two sets of opposed locations for the air cap, each with a pattern air spout hole. The pin electrode is grounded and a high dc voltage is applied to the annular electrode.
