る。 In use, the liquid inflow pipe 3 and air inflow pipe 5 of the nozzle body 1 are connected to respective required pipes (not shown), and a mold release agent, for example, is introduced from the liquid passage 2 of the liquid inflow pipe 3. Then, air is introduced from the air passage 4 of the air inlet pipe 5, and the mold release agent is atomized and ejected with the air. At this time, the liquid passage 2 is opened and closed by a valve 9 formed in the nozzle cylinder 6. That is, the nozzle tube 6 is moved into the nozzle body 1 by the pressure of the air introduced from the air passage 4 against the pressing force of the pressing spring 8.
When the valve 9 is moved toward the tip opening 10 of the nozzle tube 6, the valve 9 formed in the nozzle tube 6 moves to the same body, so the liquid outlet 3'a of the liquid inlet pipe 3 opens and the liquid flows out. The atomization is carried out within the nozzle cylinder 6 by air introduced from the air passage 4. Then, when the air is stopped, the pressure of the pressure spring 8 pushes back the valve 9 together with the nozzle cylinder 6, and the liquid outlet 3'a of the liquid inlet pipe 3 is closed, and the liquid stops flowing.

くなる。 In addition, the amount of ejection can be adjusted by rotating the adjustment cylinder 7 to adjust the gap L between the adjustment cylinder 7 and the nozzle cylinder 6, and by adjusting the amount of movement (gap L) of the nozzle cylinder 6, the valve 9 can be adjusted. The amount of ejection is finely adjusted by changing the opening degree between the liquid inlet pipe 3 and the liquid outlet port 3'a of the liquid inlet pipe 3. Therefore valve 9
A plate-shaped valve may be used, or a needle valve as shown in the illustrated embodiment may be used.Using the needle valve 9 makes it easier to finely adjust the degree of opening with respect to the liquid outlet 3'a.
＜考案の効果＞
本考案スプレーノズルは斯様に構成したので、
その構造が簡単で部品点数が少なくて済み、製造
組立が容易で安価に提供し得ると共に、小型軽量
