Toilet fill valve with adjustable bowl fill flow
A toilet fill valve, toilet, and associated methods are provided with an adjustable bowl fill flow. In one embodiment, a toilet fill valve includes a water inlet and a first water outlet configured to supply water to a toilet tank. A bowl fill outlet port extends from a portion of a body of the toilet fill valve, the bowl fill outlet port being operatively coupled to the water inlet. The toilet fill valve includes a bowl fill valve having a bowl fill valve inlet port and a bowl fill valve outlet port, wherein the bowl fill valve inlet port is compatible with the bowl fill outlet port and the bowl fill valve inlet port being coupled to the bowl fill outlet port, the bowl fill valve radially extending from a portion of a body of the toilet fill valve. The bowl fill valve is configured to supply an adjustable flow of water out the bowl fill outlet port for filling a toilet bowl during a flush cycle of a toilet.
1. A method for providing an adjustable bowl fill water flow in a toilet fill valve, comprising the steps of:
operatively coupling an integrally molded bowl fill outlet port to a water inlet of the toilet fill valve;
radially extending the integrally molded bowl fill outlet port from a portion of a body of the toilet fill valve, the integrally molded bowl fill outlet port comprising an integrally molded portion of the body of the toilet fill valve;
coupling an integrally molded bowl fill valve inlet port comprising an integrally molded portion of a bowl fill valve directly to the integrally molded bowl fill outlet port by establishing direct contact between the integrally molded bowl fill outlet port and the integrally molded bowl fill valve inlet port, the integrally molded bowl fill valve inlet port being compatible with the integrally molded bowl fill outlet port, the integrally molded bowl fill valve being configured to provide for the adjustable bowl fill water flow out a bowl fill valve outlet port of the integrally molded bowl fill valve for filling a toilet bowl during a flush cycle of a toilet;
providing for a configuration of the coupling between the integrally molded bowl fill valve inlet port and the integrally molded bowl fill outlet port that withstands a repeated pressure head created at the integrally molded bowl fill valve inlet port during a life cycle of the toilet fill valve without separation;
wherein the step of coupling of the integrally molded bowl fill valve inlet port of the bowl fill valve directly to the integrally molded bowl fill outlet port further comprises the steps of:
mating at least one locking ear with a corresponding at least one locking groove, respectively, the at least one locking ear being situated in a locking position of the at least one locking groove, the locking groove comprising a J formation; and
compressing a sealing ring between an end of the integrally molded bowl fill valve inlet port and a seat of the integrally molded bowl fill outlet port, wherein the compression of the sealing ring pushes the at least one locking ear into the locking position.
