Abstract (en)
In an apparatus for spraying liquid drops, two pressure chambers (10n and lOn-1) having the adjacent nozzle holes (11a), respectively start pressurization from time T1, end pressurization at time T2, and hold its state until T3. Then, pressure reducing is started from time T3, and pressure reducing is ended at time T4, and the cycle for the next pressurization is repeated. In a duration from a time T3 when one pressure chamber (10n) starts pressure reducing to time T5 when the next pressurization is started, time T1 (-1) for starting pressurization of the other pressure chamber (10n-1) is set. In this manner, the flow from one liquid introducing hole (12) back to the common flow path (20) can be reduced when the other introducing hole is subjected to such back flow. When the back flow caused by the other pressure chamber (10n-1) starting pressurization reaches the introducing hole (12) of one of the adjacent pressure chambers 10n, one pressure chamber 10n enters a state in which pressure reducing is started. Liquid inflow due to pressurization is performed smoothly, charging can be completed within a short period of time, and the time per cycle is reduced, whereby a large amount of spraying can be performed. <IMAGE>
