Abstract: A vertical float valve for use in a fluid reservoir. The vertical float valve able to open and closed based upon the level of fluid within the fluid reservoir. The vertical float valve having a body portion. The body portion attached to a float portion via a four bar (4-bar) linkage.

Abstract: A cut-off valve assembly for use with a toilet tank, includes a float within the toilet tank, a water retaining float guide within the toilet tank which allows the vertical travel of the float, the water retaining float guide having weep holes below the lowest travel of the float. The weep holes slowly release the retained water when the water in the tank is below the weep holes, a magnet within the toilet tank, affixed to the bottom of the float, and a magnetically activated cut-off valve for cutting off the water flow to the toilet tank when activated by the magnet. The magnet will activate the magnetically activated cut-off valve when the float is at the lowest travel. A preferred form of the cut-off valve assembly also includes a stem affixed to the float and extending downward from the float. The magnet is affixed to the bottom of the stem, and the magnet is affixed to the float through the stem. In a preferred form, a magnet housing is affixed to the bottom of the stem.

Abstract: A float assembly for a ball cock assembly for a flush tank of a toilet includes an inner float component which is a buoyant element operatively connected to a shutoff valve atop a standpipe supplying water to the tank. The inner float component is disposed in an outer float component which is in the general form of a container disposed within the flush tank so that its top edge is at a selected water level. In the tank-filling portion of a flush cycle, when the water rises to the selected level, the outer float component suddenly becomes filled with water, causing the inner float element to abruptly rise, shutting off the flow of water into the flush tank. In this manner, the buoyant element is caused to rise at a rate which is greater than a rate at which the water is rising in the tank.

Abstract: A flush tank tool for replacing a ballcock assembly in the flush tank of a toilet, which is in the form of a tubular member of rubber-like material formed over a metal core and being closed so that insertion of the tool into the ballcock assembly hole at the bottom of a flush tank will plug the hole against loss of residual water in the tank.
