Title:
LIQUID LEVEL CONTROL APPARATUS
Document Type and Number:
Japanese Patent JPS5235099
Kind Code:
A
Abstract:
A system for controlling the liquid level in a tank such as a fuel tank. The system includes a main inlet valve and a jet level sensor mechanism. Redundant relay valves which are fluid-pressure responsive are interconnected between the inlet valve and the jet level sensor to cause the inlet valve to shut off when the fluid within the tank reaches a pre-determined level. The inlet of the jet level sensor is connected through a pair of shut-off valves to the inlet valve to thus provide a source of liquid to flow through the jet level sensor. The shut-off valves are connected to be responsive to an over pressure condition which might exist in the tank which is being filled or an over pressure condition at the inlet resultant from excessive fluid pressure at the source thereof.
