Multihead type spray gun

Abstract

Abstract PURPOSE:To obtain the titled spray gun wherein the change of a coated pattern is made broad by setting at least three pieces of spray guns so that the amount to be jetted can be respectively controlled and driving them by compressed air fed from the same feed source. CONSTITUTION:In case of opening an air valve 5 and feeding compressed air to the air path 10 of a main body 1, the air is introduced through an air chamber 11 and passed through the hollow part of a valve pipe 19 and jetted to the inside of the jetting hole 17 of a jetting nozzle 18. In case of simultaneously sliding a piston 20, the valve pipe 19 is transferred and the jetting hole 17 is opened and paint incorporated in a paint chamber 16 is jetted to the outside of the main body 1 through the jetting hole 17. Further in case of closing the air valve 5, the jet of paint is stopped. Three or more pieces of spray gun having such a fundamental structure are parallel provided mutually and independently, and paint having respectively different color is jetted from these guns. In case of controlling both the distance between the surface to be coated and these nozzles, and the amount of each paint to be jetted, a broad change is obtained in a coated pattern and the color after completion of the coating.
