    摘要： A valve unit in an ink supply channel of an ink-jet recording apparatus, the ink supply channel having an upstream side and a downstream side, the valve unit having a diaphragm valve having a thin elastic diaphragm operating in response to pressure difference between an upstream side and a downstream side of the diaphragm, a valve body formed on the surface of the thin elastic diaphragm and having an opening therein, and an elastic support portion integrally formed with the valve body for urging the valve body toward the upstream direction, a valve seat disposed in the ink supply channel upstream of the diaphragm and kept in elastic contact with the opening, and a flow-channel forming plate for forming a flow channel disposed on the downstream side of the valve seat, the flow channel, extending in a longitudinal direction of the elastic portion and the flow channel forming plate having an end portion side extending in an upstream direction to form a flow channel whose sectional area decreases in the longitudinal direction.

    摘要： An ink cartridge for a printing apparatus providing ink to a print head through a tapered ink supply needle and removably attached to the print head. The ink cartridge includes an ink chamber for containing ink, an ink supply port, a packing member and a valve device. The ink supply port supplies ink from the ink chamber to the print head of the printing apparatus, the ink supply port including an external opening. The packing member is provided in the ink supply port and forms an ink channel for allowing a flow of ink. The packing member seals the ink supply needle of the printing apparatus by fitting therewith. The valve device is contained in the ink supply port and elastically abuts against the packing member. The valve device selectively opens and closes the ink channel in conjunction with the ink supply needle.

    摘要翻译： 一种用于通过锥形供墨针向打印头提供墨水并可移除地附接到打印头的打印设备的墨盒。 墨盒包括用于容纳墨水的墨水室，墨水供应口，密封件和阀门装置。 供墨口将墨水从墨水室供应到打印装置的打印头，供墨口包括外部开口。 填料构件设置在供墨口中并形成用于允许油墨流动的油墨通道。 包装部件通过与其配合来密封打印装置的供墨针。 阀装置容纳在供墨口中并且弹性地抵靠包装件。 阀装置与供墨针一起选择性地打开和关闭墨水通道。
