A liquid dispenser includes liquid supply, dispensing, and return channels. A portion of a first wall of the liquid dispensing channel defines an outlet opening. A second wall of the liquid dispensing channel, positioned opposite the first wall, extends along a portion of the liquid supply and return channels. Liquid supply and return passages are provided that extend through the second wall in fluid communication with the liquid supply and return channels, respectively. The liquid return passage overlaps the outlet opening of the liquid dispensing channel as viewed from a direction perpendicular to a surface of the first wall of the liquid dispensing channel. A liquid drop is caused to be ejected from the outlet opening of the liquid dispensing channel by selectively actuating a diverter member to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel. |
