えされる。BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, when an opening / closing valve of an aerosol device is opened to inject an aerosol content, the aerosol content enters a pressure chamber from an inlet of a cylinder and raises the pressure of the pressure chamber. The piston is moved by the increase in the pressure, and when the piston moves by a predetermined amount, the communication means connects the pressure chamber and the ejection port. As a result, the aerosol content in the pressure chamber is ejected to the outside. When the aerosol contents are injected in this way, the pressure in the pressure chamber drops, so the piston is pushed back by the returning means,
The communication between the pressure chamber and the communication means is again cut off. With the above, one cycle is completed, and a fixed amount of aerosol content is sprayed to the outside in each cycle. The above cycle is repeated while the opening / closing valve of the aerosol device is open.

る。In the present embodiment, when the button 3 is pushed in, the aerosol content is transferred to the stem 4, the injection port 14 and the through hole 43.
Through the second pressure chamber 42. When the pressure in the second pressure chamber 42 increases, as shown in FIG.
Is pushed down, and the second through hole 48 opens into the second pressure chamber 42 (at this time, the other end 47 of the first through hole 44 is closed by the cylinder wall). Then, the aerosol content is the second
It is injected into the pressure chamber 23 through the through hole 48 and the first through hole 44. Thus, when the pressures in the pressure chamber 23 and the second pressure chamber 42 both rise, the pressure receiving area of the piston 15 on the pressure chamber 23 side is larger than the pressure receiving area of the second pressure chamber 42 side by the rod cross-section integral. Therefore, the piston 15 moves as shown by the chain line. When the piston 15 moves in this way,
Since the other end opening 47 of the first through hole 44 communicates with the communication passage 49, the aerosol content is ejected from the ejection nozzle 19 which is the ejection port to the outside. When the pressure in the pressure chamber 23 drops due to the injection of the aerosol content, the piston 15 drops again and the solid line in FIG. After that, while the aerosol content is being ejected from the aerosol device 2, the above operation is repeated and the aerosol content is intermittently ejected.
