Abstract

A flush valve assembly, comprising an inlet configured to receive inlet source water; an outlet configured to deliver flush water to a sanitaryware fixture; a housing; and a waterway insert configured to be positioned within the housing, wherein the housing comprises a first side opening configured to align with the flush valve assembly inlet, the housing comprises a bottom opening configured to align with the flush valve assembly outlet, the waterway insert comprises a first side opening configured to align with the housing first side opening, and the waterway insert comprises a bottom opening configured to align with the housing bottom opening.

Claims (33)

1 . A flush valve assembly, comprising

an inlet configured to receive inlet source water;

an outlet configured to deliver flush water to a sanitaryware fixture;

a housing; and

a waterway insert configured to be positioned within the housing,

wherein

the housing comprises a first side opening configured to align with the flush valve assembly inlet,

the housing comprises a bottom opening configured to align with the flush valve assembly outlet,

the waterway insert comprises a first side opening configured to align with the housing first side opening,

the waterway insert comprises a bottom opening configured to align with the housing bottom opening, and

the waterway insert comprises a vertical rib configured to protect a piston or diaphragm valve assembly from a force of the inlet source water.

2 . The flush valve assembly according to claim 1 , wherein the waterway insert comprises an upper opening configured to receive the piston or the diaphragm valve assembly, and wherein the housing comprises an upper opening configured to align with the waterway insert upper opening.

3 . The flush valve assembly according to claim 1 , wherein the waterway insert comprises a second side opening configured to receive a manual actuator assembly, and wherein the housing comprises a second side opening configured to align with the waterway insert second side opening.

4 . The flush valve assembly according to claim 1 , wherein the waterway insert includes a valve seat.

5 . The flush valve assembly according to claim 1 , wherein the waterway insert comprises a water channel configured to be associated with a manual actuator assembly.

6 . The flush valve assembly according to claim 1 , comprising a piston valve assembly.

7 . The flush valve assembly according to claim 1 , wherein the vertical rib comprises a horizontal extension, the horizontal extension extending in the flow direction of the inlet source water.

8 . The flush valve assembly according to claim 2 , comprising a bonnet nut configured to couple to the waterway insert upper opening.

9 . The flush valve assembly according to claim 1 , wherein

the housing comprises a first material,

the waterway insert comprises a second material, and

the first material is different than the second material.

10 . The flush valve assembly according to claim 9 , wherein the first material comprises a metal and the second material comprises a thermoplastic.

11 . The flush valve assembly according to claim 9 , wherein the waterway insert comprises an engineering thermoplastic.

12 . The flush valve assembly according to claim 9 , wherein the waterway insert comprises a glass-filled thermoplastic.

13 . The flush valve assembly according to claim 9 , wherein the waterway insert comprises stainless steel.

14 . The flush valve assembly according to claim 9 , wherein the housing comprises zinc.

15 . The flush valve assembly according to claim 1 , wherein the housing comprises an overmold outer layer.

16 . The flush valve assembly according to claim 15 , wherein the overmold outer layer comprises zinc.

17 . The flush valve assembly according to claim 1 , wherein the housing comprises a unitary construct.

18 . The flush valve assembly according to claim 1 , wherein the housing comprises a sectional construct.

19 . The flush valve assembly according to claim 1 , wherein the waterway insert comprises a unitary construct.

20 . The flush valve assembly according to claim 1 , wherein the waterway insert comprises a unitary injection molded part.
