ABSTRACT:
The automatic fill-stop valve passes the liquid filling a tank. A level-sensing tube passes vapor until the tank liquid level rises that high, and, thereupon, passes liquid. Serial orifices in the sensing passage produce a valve closing signal when the liquid level reaches the sensing tube to automatically stop the filling of the tank.
