    • According to one embodiment, a droplet ejection head includes a liquid room, chambers, piezo elements, restrictors, movable pieces, and actuators. The liquid room stores a liquid. The chambers are supplied with the liquid from the liquid room and include nozzles for ejecting the supplied liquid in a droplet state. The piezo elements can be displaced in directions so as to change contents of the chambers. The restrictors bring the liquid room and the chambers in communication with each other. The movable pieces are movable in directions so as to change flow-path areas of the restrictors. The actuators move the movable pieces in the directions so as to change the plow-path areas of the restrictors.
    • 根据一个实施例,液滴喷射头包括液体室,室,压电元件,限流器,可动件和致动器。 液体储存液体。 这些室从液体室供应液体,并且包括用于以液滴状态喷射所提供的液体的喷嘴。 压电元件可以在方向上移位,以便改变腔室的内容物。 限流器使液体室和室彼此连通。 活动件可沿方向移动,以便改变限流器的流路面积。 致动器沿可移动的方向移动以便改变限制器的犁道区域。
