    • A high efficiency, liquid supply vessel is provided. The liquid supply vessel includes a chamber, either an open-foam or septum-based fluidic interconnect, a tower, and at least one gas-permeable vent. The tower includes a valve which remains closed when the vessel is inserted into a printer and the fluidic interconnect is engaged, thereby retaining the liquid in the vessel. When the printhead is operated, a sufficient vacuum is created to open the valve, thereby supplying the liquid to the printhead. Whereas the vacuum pressure may otherwise rise to unacceptable levels, the gas-permeable vent enables the pressure to be equalized. Similarly, the vent equalizes pressure during altitude and/or temperature changes, thereby preventing pressure increases or decreases which would otherwise be associated with such changes.
    • 提供了高效率的液体供应容器。 液体供应容器包括室,基于开泡泡或隔膜的流体互连,塔和至少一个透气的通气口。 塔包括当容器插入打印机并且流体互连件接合时保持关闭的阀,从而将液体保持在容器中。 当打印头被操作时,产生足够的真空来打开阀,从而将液体供应到打印头。 尽管真空压力可能会升高到不可接受的水平,但是透气通气孔使压力相等。 类似地,排气口在高度和/或温度变化期间均衡压力,从而防止压力增加或减小,否则这将与这种变化相关联。
