<P>PROBLEM TO BE SOLVED: To provide a spray gun which can adjust a mixing proportion of liquid conveniently and accurately and does not allow the liquid in a mixed state to remain within the body. <P>SOLUTION: In the trigger type spray gun, a piston is subjected to reciprocating motion by dragging a lever and the liquid in a vessel is sucked and pressurized and is sprayed from an injection nozzle. Therein, the trigger type spray gun is provided with the piston having at least two pressure-receiving bodies and at least two cylinders which allow the respective pressure-receiving bodies to be fitted slidably so as to perform liquid suction and form a pressurizing space. A mixing path for mixing the liquid pressurized by the respective cylinders and forcibly feeding the mixed liquid toward the injection nozzle is disposed between a discharge path of the cylinder and the injection nozzle connected with the discharge path. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
