PURPOSE:To perform reliable control of a spraying amount, by installing a moving control part which can shut off at least a part of jet in a smooth flow range. CONSTITUTION:Water, sucked in a pump 3 through a water feed pipe 2 from a tank 1, is pressurized and fed to a nozzle 4, and is radially injected through a nozzle 4a in a spraying chamber 5. A position of a colliding material 5a is set so that it collides in a drop shape range, and water collides and is sprayed therein. Meanwhile, the air is fed from a fan 7 through an air port 8 into the spraying chamber 5, where sprayed particle is graded and carried and exhausted through a nozzle 6. A control body 9 is adapted to be turned by a regulating knob 11, and jet is caused to collide in a smooth flow range for shutting-off. This enables reliable control of a spray amount. |
