スプレイガンの塗料圧力制御装置。 A reciprocating pump driven by an air motor feeds high-pressure liquid paint to the spray gun, and the liquid paint is ejected from the nozzle at high speed. The paint chamber of the accumulator is connected to the paint chamber separated by a movable actuating body to the paint chamber side and the air chamber side, and the air chamber of the accumulator is used to supply pressurized air to the air motor. When the reciprocating pump reaches bottom dead center or top dead center and the pressure of the liquid paint in the pumping path decreases slightly, the actuating body enters the paint chamber and pumps the liquid. A paint pressure control device for an airless spray gun characterized by a configuration that prevents a significant drop in paint pressure.
