エアースプレーにもそのまゝ適用できる。When the operating lever 3 is pulled, the interlocking lever 31 pushes the cap 22 and pushes the valve rod 16 downward against the elastic force of the spring 24, so that the packing 25 of the step 6a moves away from the upper end of the cavity 5 and comes out of the compressed air connection port 32. When the compressed air enters the inside from the outer peripheral surface of the cylindrical air filter 10 through the air passage 34, it removes dust, water, oil, etc. in the compressed air, passes through a large number of small holes 8a of the cylinder 8, and from the upper end of the cavity 5. Clean air is jetted from the nozzle 2 through the air passage 35 after entering the space 19. At the same time, the drain valve 2 under the valve rod 16
Since 7 opens the valve seat 28 and closes the lower valve seat 29, the water accumulated in the lower part of the water reservoir 36 at this short time is instantaneously generated by the compressed air injected from the vertical groove 12a of the collar 12 into the water reservoir 36. Through the valve seat 28 and the valve seat 29, and through the through hole 30 at the lower end of the valve rod 16 to be drained from the drain port 26. That is, every time the operation lever 3 is pulled, the water in the compressed air accumulated in the water reservoir 36 is instantaneously discharged. The present invention can be applied to the air spray as well as the air gun.
