Adjustable flat pattern powder spray gun.

摘要

An electrostatic spray gun (10) for spraying solid particulate powder materials entrained in a gas medium in a flat pattern including an electrically non-conductive housing (16) and a nozzle (12) to which is rotatably mounted an orifice restricting element (61) with a pair of edges (75) which move across the nozzle orifice (49) as the element (61) is rotated to adjustably restrict the orifice (49) and thereby vary the width of the flat powder spray pattern.
