AI Technical Summary
Technical Problem
Existing toilet tank fill valves suffer from issues such as debris accumulation, large size, reliance on float mechanisms, and inefficiencies in flow rate and pressure handling, leading to potential failure and space constraints.
Method used
A piston-based fill valve design that utilizes a pressure chamber and diaphragms to control water flow without a float, using a venturi effect to maintain the valve in open or closed positions with minimal force, and a vacuum chamber to balance air pressure for precise control.
Benefits of technology
The design achieves efficient water flow at varying pressures, reduces space requirements, and minimizes mechanical wear, providing a compact and reliable fill valve operation.

Abstract
A filling valve with a pressure chamber having an open bottom end and a diaphragm at an upper end such that the falling water level in the bath tank causes the diaphragm to bend in a first direction, thereby moving a sealing member to an open position, with a venturi in the sealing valve holding the sealing member in the open position until the water filling the tank causes the diaphragm to bend in a second direction, thereby moving the sealing member back to the closed position.
