Abstract
A liquid dispenser is provided that includes a liquid supply channel, a liquid dispensing channel, and a liquid return channel. The liquid dispensing channel includes a wall. The wall includes a surface. A portion of the wall defines an outlet opening that includes a downstream edge relative to a direction of liquid flow through the liquid dispensing channel. The downstream edge is sloped relative to the surface of the wall of the liquid dispensing channel. A liquid is provided that flows from the liquid supply channel through the liquid dispensing channel to the liquid return 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.
