Abstract
A liquid dispenser includes a liquid supply channel and a liquid ejector channel that includes an outlet opening. A liquid supply provides a flow of a pressurized liquid through the liquid ejector channel from the liquid supply channel. The pressurized liquid has a momentum as the liquid moves through the liquid ejector channel. A liquid return channel receives the liquid after the liquid passes through the liquid ejector channel. A diverter member forms at least a portion of a wall of the liquid ejector channel. A portion of the diverter member is selectively movable away from the liquid flowing through the liquid ejector channel. The momentum of the liquid causes some of the liquid to be diverted through the outlet opening when the portion of the diverter member is moved away from the liquid flowing through the liquid ejector channel.
