A liquid dispenser includes a liquid supply channel, a liquid dispensing channel including an outlet opening including an end, and a liquid return channel. A liquid supply provides liquid under pressure from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A diverter member is selectively actuatable to divert a portion of the liquid toward outlet opening of the liquid dispensing channel. A structure extends from the end of the outlet opening and is shaped to direct the portion of the liquid diverted from the liquid dispensing channel through a steep angle relative to the direction of travel of the liquid provided by the liquid supply channel.
