摘要： 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.

摘要： A jetting module includes a nozzle plate, a thermal stimulation membrane, and an enclosure. Portions of the nozzle plate define a nozzle. The thermal stimulation membrane includes a plurality of pores. The enclosure extends from the nozzle towards the thermal stimulation membrane to define a liquid chamber positioned between the nozzle and the thermal stimulation membrane. The liquid chamber is in fluid communication with each of the nozzle and the plurality of pores. The liquid chamber is spanned by a portion of the thermal stimulation membrane. A source provides a liquid under pressure through the thermal stimulation member with the pressure being sufficient to jet a stream of the liquid through the nozzle after the liquid flows through the thermal stimulation membrane.

摘要： 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.

摘要： Each liquid dispensing element of an array includes liquid supply, dispensing, and return channels positioned on a substrate. The liquid dispensing channel, in communication with the supply and return channels, includes an outlet opening and is associated with a diverter member. Liquid supply and return passages, in communication with liquid supply and return channels, respectively, extend through the substrate. Liquid supply and return ducts of a liquid manifold are in communication with each liquid supply passage and liquid return passage, respectively. Liquid flows from the liquid supply duct through each liquid dispensing element to the liquid return duct. A liquid drop is ejected from the outlet opening of the liquid dispensing channel of one of the liquid dispensing elements by selectively actuating the associated diverter member to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.
