Abstract
The fill valve and assembly provides an elongated cylindrical water supply tube and a valve seat disposed atop the water supply tube. The valve seat comprises a circular inner valve seat portion and a circular outer valve seat portion between which extend support structures in the form of a plurality of lands and spokes. A bridge is disposed in the center of the valve seat structure about the inner valve seat portion and atop the plurality of lands and spokes. A main diaphragm valve is disposed atop the valve seat structure such that the bridge is disposed between the valve seat structure and the main diaphragm valve. The present invention provides for a thinner and softer durometer EPDM material for the main diaphragm which is advantageous for improved function while the bridge prevents the thin section of the main diaphragm valve from being abraded or cut when high pressures try to push the diaphragm into the spokes.
