    Abstract: A drop-on-demand ink jet printing system includes an ink channel having a nozzle orifice through which ink droplets are ejected when ink in the ink channel is subjected to a momentary positive pressure wave. An ink feed passage opens into the ink channel to transport ink into the channel from an ink reservoir. A selectively-actuated valve, associated with the ink feed passage, restricts the flow of ink through the ink feed passage when actuated. The valve is actuated in timed association with the momentary pressure wave, whereby flow of ink past the valve from the ink channel towards the reservoir is inhibited. The ink feed passage may be a microfluidic channel, and the selectively-actuated valve a heater in thermal contact with at least a portion of the associated microfluidic channel, whereby thermally-responsive ink in the ink feed passage can selectively be heated by the heater such that the thermally-responsive ink will be caused to increase in viscosity to thereby restrict backward ink flow through the ink feed passage. The ink may be comprised of a carrier having a tri-block copolymer of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide).

    Abstract translation: 一种按需喷墨打印系统包括具有喷嘴孔口的墨水通道，当墨水通道中的墨水经受一瞬间的正压波时，喷墨口喷射墨滴。 墨水供给通道通向墨水通道，以将油墨从墨水储存器输送到通道中。 与供墨通道相关联的选择性致动的阀限制当致动时油墨通过供墨通道的流动。 阀门与瞬时压力波定时关联起动，从而阻止墨水从墨水通道流向储存器的墨水流过阀门。 供墨通道可以是微流体通道，并且选择性致动的阀是与相关联的微流体通道的至少一部分热接触的加热器，由此，供墨通道中的热响应性油墨可以选择性地被加热器加热 导致热响应性油墨的粘度增加，从而限制向后墨水通过供墨通道。 油墨可以由具有聚（环氧乙烷） - 聚（环氧丙烷） - 聚（环氧乙烷）的三嵌段共聚物的载体组成。
