摘要： A liquid dispenser includes a liquid supply channel including an exit having a cross sectional area, a liquid return channel, and a liquid dispensing channel including a cross sectional area and an outlet opening. The outlet opening includes an end that is adjacent to the liquid return channel. The cross sectional area of a portion of the liquid dispensing channel that is located at the end of the outlet opening is greater than the cross sectional area of the exit of the liquid supply 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.

摘要： A drop on demand ink jet print head has a chamber with a plurality of liquid passages into and out of said chamber, such that liquid is continuously moved into the chamber to a stagnation point adjacent to the nozzle opening, whereat the fluid comes substantially to rest, and out of the chamber from the stagnation point such that vector sum of liquid flow derived forces within the liquid channels is neutral. An actuator associated with the chamber is adapted to selectively increase the pressure of the liquid at the stagnation point to thereby eject a liquid drop from the nozzle opening. Continuous fluid flow internal to the system decreases the time to refill the fire chamber directly behind the nozzle opening after droplet ejection. This in turn dramatically increases the response time of the system.

摘要： A nozzle for a drop ejector is shaped as a plurality of lobes adjoining a central opening region and extending along a radial direction away from the central region. Each lobe increases in width as distance from the central region increases. The nozzles include sidewalls that converge toward the central opening region of the nozzle, giving the lobe a teardrop shape. Because the central part of the nozzle opening is constricted the ink that is ejected pinches off in the center and provides several advantages such as straighter trajectory, shorter tails, better accuracy, smaller ink volume, and less satellite effects.

摘要： A printhead includes a catcher and a negative pressure source. The catcher includes a liquid drop contact structure. The liquid drop contact structure includes a plurality of pores, each of the plurality of pores having a substantially uniform size when compared to each other. The plurality of pores have a critical pressure point above which air can displace liquid from the plurality of pores. The negative pressure source is in fluid communication with the plurality of pores of the liquid contact structure. The negative pressure source includes a pressure regulator to control the negative pressure such that the negative pressure remains below the critical pressure point of the plurality of pores of the liquid drop contact structure.
