Abstract

THE LIQUID LEVEL CONTROL DEVICE INCLUDES CASING (1) NESTED BETWEEN TWO FLOATS (2, 10). FLOAT (10) FITS INSIDE CASING (1) AND CONTROLS WATER FLOW THROUGH INLET (3) VIA CLOSURE (12). THE BASE OF CASING (1) HAS PORTS (17) TO ALLOW WATER TO FLOW INTO A CONTAINER. FLOAT (2) IS AFFECTED BY THE LEVEL OF WATER IN THE CONTAINER AND OPENS/SHUTS VENT (8) VIA CLOSURE (9). WHEN THE WATER LEVEL IS LOW, FLOAT (10) CAUSES CLOSURE (12) TO OPERATE AND FEED WATER INTO CASING (1) AND OUT PORTS (17) INTO THE CONTAINER. AS THE WATER LEVEL RISES, FLOAT (10) IS HELD DOWN BY AIR TRAPPED INSIDE CASING (1) BY VENT (8) BEING CLOSED. AS FLOAT (2) BECOMES BUOYANT, IT RISES TO OPEN VENT (8). FLOAT (10) THEN RISES AND SHUTS OFF THE WATER FLOW. WHEN THE WATER LEVEL FALLS, FLOAT (2) LOWERS AND SEALS VENT (8).IF THE WATER LEVEL CONTINUES TO DROP A PARTIAL VACUUM IS CREATED INSIDE CASING (1) AND MAINTAINS THE WATER LEVEL THEREIN.WHEN THE WATER LEVEL FALLS BELOW ENTRY (16), AIR ENTERS INTO CASING (1) THROUGH BREATHER TUBE (6) AND HOLE (15) TO RELIEVE THE PARTIAL VACUUM. FLOAT (10) DROPS AND OPENS INLET (3) TO RESTART THE WATER FILLING CYCLE.
