Abstract
An electrostatic spray gun particularly adapted to the spraying of fast-drying paint mixtures while preventing the polymerization or setting up of the paint mixtures includes a gun body having defined therein a gun inlet for receiving paint, a gun spray orifice, an annular seat surrounding the orifice, and a supply passage communicating the gun inlet and the orifice. The gun also includes a valve assembly including a reciprocable valve member engageable with the valve seat to close the orifice and define a closed position of the valve member. The valve assembly further includes an electrode extending from the valve member through the orifice. The gun further includes an adjustable control structure for moving the value member between its closed position and an open position and for varying a distance between the valve seat and the valve member when the valve member is in its open position so that a resistance to flow through the supply passage is varied and a rate at which paint flows out of the orifice is varied.
