摘要：
A liquid dispenser includes an array of liquid dispensing elements positioned on a substrate is provided. Each liquid dispensing element includes a liquid dispensing channel positioned on the substrate. The liquid dispensing channel includes an outlet opening positioned on a wall opposite the substrate. A diverter member is associated with the liquid dispensing channel. A liquid return channel is positioned on the substrate in fluid communication with the liquid dispensing channel. A liquid supply channel is positioned on the substrate in fluid communication with the liquid dispensing channel. A liquid supply passage extends through the substrate and is in fluid communication with the liquid supply channel. A liquid return passage extends through the substrate and is in fluid communication with the liquid return channel. A liquid manifold is provided that includes a liquid supply duct and a liquid return duct. The liquid supply duct is in fluid communication with each liquid supply passage of each liquid dispensing element. The liquid return duct is in fluid communication with each liquid return passage of each liquid dispensing element. A liquid flows from the liquid supply duct of the liquid manifold through each liquid dispensing element to the liquid return duct of the liquid manifold. A liquid drop is ejected from the outlet opening of the liquid dispensing channel of one of the liquid dispensing elements by selectively actuating the diverter member of the liquid dispensing element to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel of the liquid dispensing element.
