    • Disclosed is a dispenser for dispensing a composition in response to level changes in a liquid in a tank. The dispenser includes a container for holding the composition, a discharge conduit in fluid communication with the container, an air inlet in fluid communication with the container, and a level sensing member mounted to the dispenser such that a lower end of the level sensing member contacts the liquid in the tank and senses its level. In use, a rise of the liquid in the tank between a lower liquid level and a higher liquid level causes the level sensing member to alter air pressure in a headspace of the container above the composition and thereby cause a controlled discharge of the composition from the discharge conduit; and a fall of the liquid in the tank between the higher liquid level and the lower liquid level causes the level sensing member to alter pressure in the headspace and thereby causing air to be vented into the headspace from the air inlet.
    • 公开了一种用于响应于罐中的液体中的液位变化分配组合物的分配器。 分配器包括用于保持组合物的容器,与容器流体连通的排放管道,与容器流体连通的空气入口以及安装到分配器的水平检测构件,使得液位感应构件的下端接触 罐中的液体并感觉其水平。 在使用中,液体在较低液位和较高液位之间的液体升高导致液位检测构件改变容器顶部空间中的空气压力高于组合物,从而导致组合物从 排放管道 并且在较高液位和较低液位之间的槽中的液体的下降导致液位感测构件改变顶部空间中的压力,从而使空气从空气入口排放到顶部空间中。
