Liquid droplet spraying apparatus |
摘要 |
A liquid droplet spraying apparatus includes: a plurality of nozzles, a plurality of pressure chambers respectively connected to the nozzles, the pressure chambers each configured to store liquid to which spraying pressure is selectively applied, a common ink chamber that stores the liquid supplied to the pressure chambers; and narrowing portions coupled between the common liquid chamber and the plurality of pressure chambers to supply the liquid therethrough. The narrowing portions are larger in a pressure loss than the common liquid chamber and the plurality of pressure chambers. A ratio of a length of each of the narrowing portions in a liquid flowing direction with respect to a length of corresponding one of the pressure chambers in the liquid flowing direction is 0.34 or more, wherein the liquid flowing direction corresponds to a direction in which the liquid flows through the narrowing portions.
