Abstract
A liquid dispenser includes a first liquid chamber and a second liquid chamber. The first liquid chamber includes a nozzle. The second chamber is in fluid communication with a liquid supply channel and a liquid return channel. A flexible membrane is positioned to separate and fluidically seal the first liquid chamber and the second liquid chamber from each other. The flexible membrane includes a bimorph actuator that causes the flexible membrane to move from a first position to a second position to eject liquid through the nozzle of the first liquid chamber. In one example embodiment, a liquid supply provides a liquid that flows continuously from the liquid supply through the liquid supply channel through the second liquid chamber through the liquid return channel and back to the liquid supply during a drop dispensing operation.
