    摘要： Disadvantages relating to ink refill specific to an increase in a number of ink ejection openings in an ink jet print head is eliminated to provide a particularly excellent fast-response capability and ejection performance. More specifically, when an ink is supplied to a liquid chamber via an ink supply path and an ink supply opening formed in a support member and a print element substrate in a print head, and is then ejected from ejection openings, a pressure of an ink effected upon the ejection is transmitted to the ink supply path. This pressure, however, can be absorbed by air chambers via communication paths to reduce adverse effects of the pressure on ink refill in the liquid path after the ejection. In this case, since the air chambers and other components are structured to be closed with respect to the atmosphere, problems such as an increase in viscosity which are associated with communication of the air chambers and other components with the atmosphere can be prevented.

    摘要翻译： 消除了与针对喷墨打印头中的多个墨水喷射口的增加有关的墨水补充相关的缺点，以提供特别优异的快速响应能力和喷射性能。 更具体地说，当通过供墨路径将油墨供应到液体室时，形成在支撑构件中的供墨口和打印头中的打印元件基板，然后从喷射口喷射墨水的压力 在喷射时实现的墨水被传送到供墨路径。 然而，该压力可以通过通气路径被空气室吸收，以减少在喷射之后液体路径中的压力对油墨再填充的不利影响。 在这种情况下，由于空气室和其它部件被构造为相对于大气封闭，所以可以防止诸如与空气室和其它部件与大气连通的粘度增加的问题。
