Abstract:
1. A fill valve comprising: a fluid flow assembly for receiving pressurized water and for having a main water flow pathway for carrying some portion of the pressurized water therethrough and a metered water flow pathway for carrying another, a metered flow portion, of the pressurized water therethrough and for expelling the two portions of pressurized water therefrom; a piston diaphragm assembly engaging the fluid flow assembly, the piston diaphragm assembly for receiving in and expelling from the metered flow portion of the pressurized water in a metered flow chamber thereof; a reset plunger meter pin assembly for fluidly engaging the fluid flow assembly and the piston diaphragm assembly to meter the flow of water into the metered flow chamber of the piston diaphragm assembly and for initiating a timed cycle of the piston diaphragm assembly, which timed cycle controls the water flowing through the fill valve; and further including means cooperating with the fluid flow assembly and the piston diaphragm assembly to increase the pressure of the metered flow portion to the piston diaphragm assembly, such increase as a function of the water pressure of the pressurized water source;
