초록

A flow regulator is disclosed for controlling liquid flow, for example, from a supply source to a receiving tank according to the liquid level in the tank. Specifically, a fluid interaction device communicating with the receiving tank causes a fluid pressure signal to be developed in response to departure of the liquid in the tank from a predetermined level. A differential pressure responsive valve adjusts liquid flow from the supply source to the receiving tank in response to the fluid pressure signal. Several embodiments and other features including a ...
