SPRAY GUN

PROBLEM TO BE SOLVED: To provide a spray gun which allows a trigger to accord with a predetermined half-opened position and can change the total flow rate of gas according to an operation of the trigger.SOLUTION: A spray gun 1 includes: a gas flow rate regulation part provided on a gas channel for supplying gas which performs atomization of liquid and pattern regulation of atomized liquid; a gas flow rate regulation part avoiding gas channel 30 which connects one end 32 thereof to the upstream side as the gas supply side rather than the gas flow rate regulation part and supplies the gas to a gas channel of the downstream side rather than the gas flow rate regulation part not through gas flow rate regulation part; and an avoiding channel gas control valve 35 which is disposed in the middle of the gas flow rate regulation part avoiding gas channel 30, performs supply of the gas and stops the supply. Therein, a pressurizing part of the avoiding channel gas control valve 35 is pressurized by a pressurizing head part 16c of the trigger 16 until the trigger 16 attains to the maximum pulling amount and the gas on the upstream side rather than the gas flow rate regulation part is supplied to the downstream side rather than the gas flow rate regulation part not through the gas flow rate regulation part.SELECTED DRAWING: Figure 1 【課題】引金を所定の半開の位置に合わせることができ、気体の総流量も引金の操作によって変えることができるスプレーガンを提供する。【解決手段】スプレーガン１は、液体の霧化及び霧化液体のパターン調節を行う気体を供給する気体流路に設けた気体流量調節部と、気体流量調節部よりも気体供給側となる上流側に一端３２が接続され、気体流量調節部を介さずに気体流量調節部よりも下流側の気体流路に気体を供給する気体流量調節部回避気体流路３０と、気体流量調節部回避気体流路３０の途中に設けられ、気体の供給及び供給停止を行う回避流路気体制御弁３５と、を備え、引金１６が最大引き量に至るまでに、回避流路気体制御弁３５の押圧部が引金１６の押圧頭部１６ｃによって押圧され、気体流量調節部を介さずに気体流量調節部よりも下流側に気体流量調節部よりも上流側の気体が供給される。【選択図】図１
