More Information
Summary:A liquid-drop spraying device is provided which can perform a stable liquid discharge without producing air bubbles in the liquid of the pressurized room as well as the amount of liquid supply per unit time is increased. The liquid can be flowed into the pressurized room uniformly and without entrainment of bubbles from the nozzle side by making an initial discharge (or charge) time constant larger than a subsequent discharge (or charge) time constant, which in turn allows liquid in the pressurized room to be replaced by slow suction followed by fast suction.
