    摘要： A pressure control device for an inkjet pen. The inkjet pen is provided with a reservoir having a first opening and maintaining a back pressure established therein. The pressure control device comprises a bag, a pressure plate, an isolation member, a bias member, and an elastic member. The bag, disposed inside the reservoir, communicates with outside the reservoir so as to expand inside the reservoir. The pressure plate is disposed inside the reservoir and adjacent to the bag so as to move inside the reservoir. The bias member is disposed inside the reservoir and adjacent to the pressure plate, the isolation member, and the reservoir respectively such that the bag expands to move the pressure plate when the back pressure inside the reservoir changes, then the pressure plate moves the bias member so that the isolation member separates from the first opening.

    摘要翻译： 一种用于喷墨笔的压力控制装置。 喷墨笔设置有具有第一开口并保持其中建立的背压的储存器。 压力控制装置包括袋，压板，隔离构件，偏压构件和弹性构件。 设置在储存器内的袋与储存器的外部连通，以便在储存器内部扩张。 压板设置在储存器的内部并且靠近袋子，以便在贮存器内移动。 偏置构件分别设置在储存器的内部并且分别邻近压力板，隔离构件和储存器，使得当储存器内部的背压改变时袋膨胀以移动压力板，然后压板移动偏压构件 使得隔离构件与第一开口分离。
