ABSTRACT:
A liquid dispenser includes a liquid supply channel, a liquid supply adapted to feed a stream of liquid through the supply channel, a liquid return channel adapted to receive liquid from the supply channel, a liquid dispensing outlet opening, and a diverter member selectively movable into the supply channel to divert droplets to the dispensing outlet opening. The liquid flows from the liquid supply channel to the liquid return channel by Coanda effect when not diverted. The motion of the diverter member is substantially orthogonal to and opposes the direction of liquid flow, so that energy associated with moving the diverter member imparts no energy to the diverted droplets. The energy associated with moving the diverter member is less than 100 nJ per pL droplet volume. In some embodiments, the energy associated with moving the diverter member is less than 10 nJ per pL droplet volume.
