Abstract

A flush valve for use with toilet devices such as urinals and water closets includes a body having an inlet and an outlet. There is a valve seat between the inlet and outlet and a barrel connects the valve seat with the outlet. A diaphragm assembly is positioned within the flush valve and movable toward and away from a closing position on the valve seat to control the flow of water to the outlet. The diaphragm assembly includes a diaphragm peripherally clamped within the flush valve housing and a refill ring extending downstream from the diaphragm. The refill ring has a plurality of circumferentially disposed passages connecting the inlet and outlet when the diaphragm assembly is away from the valve seat. The size of the passages in the refill ring determines the volume of water flow during operation of the flush valve.
