    • A dispenser and method for dispensing a liquid. The dispenser (10) includes a barrel (12) with an interior chamber (14) for holding the liquid (16), a discharge outlet (18) communicating with the interior chamber (14) for discharging the liquid (16), and an air space (20) for receiving pressurized air for forcing the liquid (16) from the interior chamber (14) through the discharge outlet (18). An air supply solenoid valve (70) and an air exhaust solenoid valve (72) are each operatively coupled with the barrel (12). The air supply solenoid valve (70) controls the flow of pressurized air to the air space, and the air exhaust solenoid valve (72) controls the flow of air from the air space to atmosphere. A control selectively activates the air supply solenoid valve (70) and the air exhaust solenoid valve (72) to respectively supply air to the air space and exhaust air from the air space in order to dispense desired amounts of the liquid from the discharge outlet (18).
    • 一种用于分配液体的分配器和方法。 分配器包括具有用于保持液体的内部室的筒,与内部室连通以排出液体的排出口,以及用于接收加压空气的空气空间,用于迫使来自内部室的液体通过排出口。 空气供应电磁阀和排气电磁阀各自可操作地与筒连接。 供气电磁阀控制加压空气流向空气的空气,排气电磁阀控制空气从空气到大气的流动。 控制器选择性地激活供气电磁阀和排气电磁阀,以分别向空气空间供应空气并从空气空间排出空气,以便从排放出口分配所需量的液体。
