Abstract
A low pressure atomizing spray gun is disclosed in which paint is injected from a nozzle, an opening of the nozzle is controlled by a needle valve, air is mixed with a flow of paint, air is blown from both sides after the air-paint mixture is sprayed from a spraying nozzle and it is again mixed and atomized. The nozzle is formed as circular hole with a circular outer shape, and the spray hole is designed with a lip-like shape having different dimensions in longitudinal and lateral directions and with a conical or similar shape. Lateral air holes are furnished in front of the spray hole, at opposite positions on both sides of the spray flow and function to blow the diffusing air flow toward the spray flow. A pair of longitudinal air holes is furnished to inject the secondary air obliquely from behind the spray hole and to make the air collide with the flattened spray pattern.
