Device for automatically refilling a liquid container

摘要

A device for refilling a liquid container is composed of a displacement body which is immersed in the container liquid and the hydrostatic buoyant force of which opens a filling valve which is inserted in a pipeline to a supply vessel when the level has sunk to an impermissible extent. The filling valve is opened either by direct mechanical action or by means of a signal of a load cell which responds to the buoyant force.
