Abstract

A faucet assembly including a housing body, a valve assembly received within the housing body, and a waterway assembly having a base supporting the valve assembly. A face seal is positioned between the valve assembly and the base of the waterway assembly. An upper radial seal is positioned between the valve assembly and an internal surface of the housing body, and a lower radial seal is positioned between the base and the internal surface of the housing body.

First claim

What is claimed is:

1. A faucet assembly comprising:
a housing body including a sidewall defining an opening;
a faucet valve assembly received within the opening of the housing body;
an upper annular seal supported by the faucet valve assembly and configured to engage with an internal surface of the housing body;
a base supporting the faucet valve assembly at a valve interface;
a face seal at the valve interface between the faucet valve assembly and the base;
a lower annular seal supported by the base and configured to engage with the internal surface of the housing body;
a plurality of tubular members having first and second ends, the plurality of tubular members supported by the base and configured to be in fluid communication with the faucet valve assembly; and
a mounting nut configured to removably couple to the housing body within the opening defined by the sidewall, wherein the mounting nut when tightened is configured to compress the face seal between the faucet valve assembly and the base to form a substantially fluid-tight seal.

2. The faucet assembly of claim 1 , further comprising a handle coupled to the faucet valve assembly.

3. The faucet assembly of claim 1 , wherein the housing body further includes an endwall opposite the opening formed by the sidewall smaller than the area formed by a perimeter of the sidewall.

4. The faucet assembly of claim 1 , wherein the faucet valve assembly includes a lower housing with a groove configured to receive the upper annular seal.

5. The faucet assembly of claim 4 , wherein the upper annular seal of the faucet valve assembly contacts the internal surface of the sidewall of the housing body to form a substantially fluid-tight seal.

6. The faucet assembly of claim 1 , wherein the base includes a first face, a second face, and a plurality of openings extending between the first face and the second face, the openings sized to receive the first end of each of the tubular members.

7. The faucet assembly of claim 6 , wherein the second face of the base includes a boss formed at least around the openings and extending away from a surface of the first face, the boss configured to form fit into the opening formed by the endwall of the housing body to couple to the housing body.

8. The faucet assembly of claim 7 , wherein the at least a portion of the surface of the second face of the base contacts an interior surface of the endwall of the housing body when the base and the housing body are coupled.

9. The faucet assembly of claim 1 , the base including a groove around a perimeter of the base configured to receive the lower annular seal.

10. The faucet assembly of claim 9 , wherein the lower annular seal of the base contacts the internal surface of the sidewall of the housing body to form a substantially fluid-tight seal.

11. The faucet assembly of claim 1 , further comprising a bonnet cap supported by the mounting nut, and an o-ring removably coupling the bonnet cap to the mounting nut.

12. A faucet assembly comprising:
a housing body including a sidewall defining an opening;
a valve assembly received within the opening of the housing body, the valve assembly having a lower housing with a bottom face including a plurality of openings, the lower housing including a groove around a perimeter of the lower housing;
a first o-ring received within the groove of the lower housing of the valve assembly, the first o-ring configured to sealingly engage with an internal surface of the housing body;
a base disposed within the housing body including a first face, a second face, and a plurality of openings extending between the first face and the second face, wherein the openings are configured to align with the plurality of the openings of the cartridge valve assembly;
a plurality of tubular members having first and second ends, the first ends received by the openings of the base; and
a mounting nut configured to removably couple to the housing body within the opening defined by the sidewall; and
a face seal intermediate the faucet valve assembly and the base, wherein the mounting nut when tightened is configured to compress the face seal between the faucet valve assembly and the base to form a substantially fluid-tight seal.

13. The faucet assembly of claim 12 , further comprising a bonnet cap supported by the mounting nut, and an o-ring removably coupling the bonnet cap to the mounting nut.

14. The faucet assembly of claim 12 , further comprising a handle coupled to the faucet valve assembly.

15. The faucet assembly of claim 12 , wherein the base is overmolded around the first ends of the plurality of tubular members.

16. The faucet assembly of claim 15 , wherein the base and the plurality of tubular members are formed of a cross-linked polyethylene.

17. The faucet assembly of claim 12 , further comprising a second o-ring supported by the base and configured to sealingly engage with the internal surface of the housing body, the face seal positioned intermediate the first o-ring and the second o-ring.
