期的な圧力変動を加える必要がある。 To obtain a group of droplets with a uniform droplet diameter, we apply periodic pressure fluctuations to the liquid in the container to create regular vibrations in the liquid jet coming from the orifice hole, and then divide the liquid jet according to the frequency of the vibration. There are known ways to do this. In order to generate a droplet group with a uniform droplet diameter, the optimum vibration frequency determined by the physical properties of the liquid to be made into droplets, the physical properties of the continuous phase to which the droplets are supplied, and the ejection speed of the liquid jet, etc. It is necessary to add periodic pressure fluctuations with waveforms.

がある。 Now, when applying pressure fluctuations to a container filled with liquid by the vibrations of a vibration generator installed outside the container, the seal between the vibration transmission shaft and the container, which transmits the vibrations of the vibration generator into the container, is It is essential. The sealing part is required to have two functions: not to leak the liquid inside the container to the outside, and not to distort the vibration of the vibration transmission shaft. A seal with a sliding portion is not preferable because the vibration transmission shaft is subjected to force due to frictional resistance, which distorts the waveform of the vibration to be transmitted, resulting in uneven droplet sizes. Haas uses a small-walled rubber tube for the seal [AIChE Journal, 21 ,
383 (1975)], but although this method is presumed to have little effect on the vibration of the vibration transmission shaft, it does have problems in terms of strength.
