    • Apparatus for dispensing a desired quantity by weight of a fluid material such as a liquid color printing ink for shade mixing purposes includes a container (1) for the fluid material to be dispensed, a main fluid material dispensing discharge outlet (2) on the container (1) and a secondary fluid material dispensing discharge outlet (3) on the container (1). The container further includes a movable pressure assembly plate to apply a pressure to the fluid to dispense the fluid from the discharge outlets. The secondary dispensing dischage outlet (3) incorporates a gear pump (5) which is adjustably operable to dispense a particular volume of fluid material corresponding to a particular weight of fluid material to be dispensed. The pressure plate assembly (4) includes a presser plate (21) slidably movable in the container (1) in sealed contact with side walls (1a) of the container (1) to engage directly or indirectly the upper surface of fluid material in the container (1). A piston and cylinder assembly (23) is operative to urge the plate (21) towards and away from fluid material in the container (1).
    • 用于分配所需重量的液体材料(例如用于调色目的的液体彩色印刷油墨)的流体材料的装置包括用于待分配的流体材料的容器(1),在容器上分配排放出口(2)的主流体材料 (1)和容器(1)上的第二流体材料分配排出口(3)。 容器还包括可移动的压力组件板,以向流体施加压力以从排放出口分配流体。 辅助分配排出口(3)包括齿轮泵(5),其可调节地操作以分配对应于待分配的流体材料的特定重量的特定体积的流体材料。 压板组件(4)包括可在容器(1)中可滑动地移动以与容器(1)的侧壁(1a)密封接触的压板(21),以直接或间接地接合容器(1)中的流体材料的上表面 集装箱(1)。 活塞和气缸组件(23)可操作以朝向和远离容器(1)中的流体材料推动板(21)。
