Abstract

A faucet including a molded waterway assembly having a plurality of tubes overmolded within a valve interface member.

First claim

The invention claimed is:

1. A fluid delivery device comprising:
a hot water control valve including a hot water inlet port and a hot water outlet port;
a cold water control valve including a cold water inlet port and a cold water outlet port;
a first molded waterway fluidly coupled to the hot water control valve, including a first base having a hot water inlet opening and a hot water outlet opening, and a flexible hot water tubular member having a first end and a second end, the first end of the flexible hot water tubular member being fluidly coupled to the hot water inlet opening, the second end of the flexible hot water tubular member being free to move relative to the first end of the flexible hot water tubular member, wherein the first base is overmolded around the first end of the flexible hot water tubular member;
a second molded waterway fluidly coupled to the cold water control valve, including a second base having a cold water inlet opening and a cold water outlet opening, and a flexible cold water tubular member having a first end and a second end, the first end of the flexible cold water tubular member being fluidly coupled to the cold water inlet opening, the second end of the flexible cold water tubular member being free to move relative to the first end of the flexible cold water tubular member, wherein the second base is overmolded around the first end of the flexible cold water tubular member;
a first fluid passageway extending from the hot water inlet opening, through the hot water control valve and out of the hot water outlet opening, wherein fluid travels in a first direction through the hot water inlet opening and in a second direction, different from the first direction, through the hot water outlet opening; and
a second fluid passageway extending from the cold water inlet opening, through the cold water control valve and out of the cold water outlet opening, wherein fluid travels in a third direction parallel to the first direction through the cold water inlet opening and in a fourth direction, different from the third direction, through the cold water outlet opening.

2. The fluid delivery device of claim 1 , wherein the first molded waterway and the second molded waterway are formed of a cross-linked polymer.

3. The fluid delivery device of claim 1 , wherein the hot water control valve includes a lower surface and a first locating element supported by the lower surface of the hot water control valve; and the first base of the first molded waterway includes an upper surface and a second locating element supported by the upper surface of the first base, the second locating element of the first molded waterway configured to cooperate with the first locating element of the hot water control valve to facilitate proper orientation of the hot water control valve relative to the first molded waterway.

4. The fluid delivery device of claim 1 , wherein the first molded waterway and the second molded waterway are formed of a raised temperature resistant polyethylene.

5. The fluid delivery device of claim 1 , further comprising a holder supporting the first base of the first molded waterway.

6. The fluid delivery device of claim 5 , further comprising a first registration element supported by the first base, and a second registration element supported by the holder and configured to cooperate with the first registration element to facilitate proper orientation of the first molded waterway relative to the holder.

7. The fluid delivery device of claim 1 , further comprising a first fluid coupling overmolded to the second end of the flexible hot water tubular member, and a second fluid coupling overmolded to the second end of the flexible cold water tubular member.

8. The fluid delivery device of claim 1 , further comprising an upper housing formed of a non-metallic material and including a spout having an outlet fluidly coupled to the hot water outlet opening of the first base and the cold water outlet opening of the second base.

9. A fluid delivery device comprising:
a flow directing member including an inlet port and an outlet port; and
a molded waterway fluidly coupled to the flow directing member, the molded waterway including:
a base having an inlet opening in fluid communication with the inlet port of the flow directing member, and an outlet opening in fluid communication with the outlet port of the flow directing member;
a flexible tubular member fluidly coupled to the inlet opening, the flexible tubular member having opposing first and second ends, wherein the base is overmolded around the first end of the flexible tubular member, and the second end is free to move relative to the first end; and
a fluid coupling supported by the second end of the flexible tubular member; and

a fluid passageway extending from the inlet opening, through the flowing directing member and out of the outlet opening, wherein fluid travels in a first direction through the inlet opening and in a second direction, different from the first direction, through the outlet opening.

10. The fluid delivery device of claim 9 , wherein the molded waterway is formed of a cross-linked polymer.

11. The fluid delivery device of claim 9 , further comprising a flexible outlet water tubular member fluidly coupled to the outlet opening, wherein the base is overmolded around an end of the flexible outlet water tubular member.
