  • Fill valve responsive to liquid level
    Patent number: 4522227
    Abstract: The fill valve is responsive to liquid level by passing vented vapor through serial orifices. The inlet flow is stopped by shifting a valve spool which is responsive to the pressure between the orifices. A pressure booster adjacent the vent outlet serves to momentarily shut off the outlet when pressure rises in the region of the second orifice to aid in shifting the main valve spool when system pressure is low.

  • Automatic fill-stop valve
    Patent number: 4313459
    Abstract: Inlet into propane cylinder is covered by sliding sleeve which is raised by a float when the tank level reaches desired level. Float is partly counterbalanced by lift spring and is driven into closed position by hydraulic force when motion is initiated by the float.

  • Automatic fill-stop valve
    Patent number: 4191208
    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.
