とが多かった。As mentioned above, conventionally there was only one compressed air supply passage and its adjustment device, so when the amount of air to be supplied was adjusted, the amounts of air for atomization and pattern adjustment both changed accordingly. , could not be changed independently. For this reason, it is difficult to adjust the paint mist to be evenly dispersed in one spray pattern, and the mist often results in an uneven distribution in which the spray is dense in the center and thinner in the outer periphery.
この発明は、このような問題点を解決して、均一な分布

である。In order to solve the above problems, the present invention provides a spray gun in which compressed air injection holes for atomization and pattern adjustment are provided around the paint injection hole of the nozzle, respectively.
Two compressed air supply passages communicating with the above-mentioned jet holes are provided independently, one passage leading to the compressed air jet hole for atomization, and the other passage leading to the compressed air jet hole for pattern adjustment. The configuration is such that each has an independent adjustment device.

されている。A needle valve 4 passes through the nozzle 2, and the needle valve 4 is connected to a paint injection amount adjusting device 6 provided on a grip 5.
また、ノズル２のまわりには、独立した２本の周溝７．
８が形成され、一方の周溝７は本体１の前端面に螺合し
た空気キャップ９の霧化用噴射孔１０に連通している。Further, around the nozzle 2, there are two independent circumferential grooves 7.
8 is formed, and one circumferential groove 7 communicates with an atomizing injection hole 10 of an air cap 9 screwed onto the front end surface of the main body 1.

Each of the passages 12 and 13 is arranged in a lower stage and an upper stage inside the main body 1, the lower passage 12 communicates with the circumferential groove 7 for atomization adjustment, and the upper passage 13 communicates with the circumferential groove 8 for pattern adjustment. ing.
また、各通路１２．１３の中程には、それぞれ調節弁１

空気通路２１は、その途中に開閉弁２４が設けられ、本
体１に取付けられた引金２２の操作によりその開閉弁２
４を開閉するようになっている。An on-off valve 24 is provided in the middle of the air passage 21, and the on-off valve 24 is opened by operating a trigger 22 attached to the main body 1.
4 to open and close.
この発明のスプレーガンは、以上のごときものであるか

せる。Since the spray gun of the present invention is as described above, when the trigger 22 is operated, compressed air flows through the two passages 12.
．． The paint flows out in 13 parts, and is ejected from the injection holes 10 and 11 for atomization and pattern adjustment, respectively, and sucks up the paint in the tank and ejects it from the nozzle 2, atomizes it, and sprays it into an appropriate spray. Spread it out in a pattern and spray it forward.
このとき、各調節装置１８．１９を独立に操作すること

果がある。As described above, in this invention, the compressed air supply passages leading to the injection holes for atomization and pattern adjustment are provided independently, and an adjustment device is provided for each passage, so that the atomization can be improved. The spray condition can be adjusted by adjusting the condition and pattern opening to degree independently. Therefore, there is an effect that a paint spray pattern with uniform distribution can be easily obtained.
