    • A liquid ejection apparatus ejects liquid retained in a liquid container from a liquid ejection head. The apparatus includes a liquid supply needle having an outlet line that can be connected to the interior of the liquid container, a liquid supply line connecting the outlet line of the liquid supply needle to the recording head, and a control valve provided in the liquid supply line. The control valve closes the liquid supply line when negative pressure is applied to the liquid ejection head. A seal valve is arranged between the control valve and the liquid supply needle in the liquid supply line. The seal valve seals the liquid supply line using liquid pressure applied from the control valve to the outlet line. Accordingly, the liquid is prevented from leaking from the liquid supply needle when the liquid container is separated from the liquid supply needle.
    • 液体喷射装置从液体喷射头喷射保留在液体容器中的液体。 该装置包括:液体供给针,具有能够连接到液体容器的内部的出口管,将液体供给针的出口管连接到记录头的液体供给管;以及设置在液体供给部中的控制阀 线。 当向液体喷射头施加负压时,控制阀关闭液体供应管线。 密封阀配置在液体供给管路中的控制阀与液体供给针之间。 密封阀使用从控制阀施加到出口管线的液体压力来密封液体供应管线。 因此,当液体容器与液体供给针分离时,防止液体从液体供给针泄漏。
