Faucets are typically controlled by either a single handle which utilizes a mixing valve to proportion the flow of hot and cold water to a faucet spout, or two handles which utilize individual valves to separately control the flow of hot water and cold water to the faucet spout. In the case of the standard prior art mixing valve, two inlets are provided, one each for the hot and cold water supplies. For two handle faucets, each valve typically includes only one inlet opening which fluidly communicates with the flow passageway of a valving member. One type of two handle faucet is a centerset faucet where hot and cold water valves are coupled with the spout to a sink deck through a common base.
In an illustrative embodiment of the present disclosure, a faucet assembly includes an insert configured to receive a valve cartridge and including a guide member. A base includes a receiving member supporting the valve cartridge, the base being configured to cooperate with the guide member to resist axial movement of the insert relative to the base, and to resist rotational movement in a first direction of the insert relative to the base. A retainer is coupled to the base and is configured to cooperate with the guide member to resist rotational movement in a second direction opposite the first direction of the insert relative to the base.
According to a further illustrative embodiment of the present disclosure, a faucet assembly includes a base, a waterway supported by the base, and a valve assembly fluidly coupled to the waterway. An energy directing member is supported by one of the base and the waterway and is configured to embed within the other of the waterway and the base to form a seal therebetween.
According to another illustrative embodiment of the present disclosure, a faucet assembly includes a base, a waterway supported by the base and including a receiving port, and a valve assembly fluidly coupled to the waterway. A delivery spout is supported by the base, and a conduit is received within the delivery spout. The conduit includes a first end received within the receiving port and a collar supported proximate the first end. A seal is received within the receiving port and is compressed into sealing engagement with the waterway by the collar of the conduit.
In yet another illustrative embodiment of the present disclosure, a faucet assembly includes a base having a channel, and a waterway supported within the channel of the base. A valve assembly is fluidly coupled to the waterway. An insert is configured to cooperate with the base to secure the waterway to the base. A retainer is coupled to the base, and is configured to cooperate with the guide member to secure the insert to the base.

With reference to
The base 28 is illustratively molded from a polymer. In one illustrative embodiment, the base 28 is molded from a glass filled polypropylene, such as Celstran® PP-GF 30-02, available from Ticona of Florence, Kent. Mounting nuts 40 and 42 are threadably received on the mounting shanks 30 and 32 to secure the base 28 to the sink deck 12. The mounting nuts 40 and 42 may be conventional wing nuts molded from a polymer. An escutcheon 44 is received over the base 28 and is illustratively formed of a metal, such as plated brass or zinc. The handles 14 and 16 and the delivery spout 26 are supported above the escutcheon 44. An outlet conduit 46 defines the mixed water outlet 24 and is illustratively received within the delivery spout 26. The outlet conduit 46 is fluidly coupled to the waterway 22.
The waterway 22 includes a hot water coupler 50 and a cold water coupler 52. The hot water coupler 50 includes the hot water supply tube 36 and a hot water outlet tube 54. A connector 56 fluidly couples the hot water supply tube 36 and the hot water outlet tube 54 through the hot water control valve cartridge 18. More particularly, the connector 56 fluidly couples the hot water supply tube 36 to the inlet of the valve cartridge 18, and fluidly couples the outlet of the valve cartridge 18 to the hot water outlet tube 54. Operation of the valve cartridge 18 controls the flow rate of hot water from supply tube 36 to outlet tube 54. In one illustrative embodiment, the hot water supply tube 36 and the hot water outlet tube 54 are formed of a polymer, such as polyethylene, and the connector 56 is an overmold formed of a polymer, such as polyethylene, molded around proximal ends of the tubes 36 and 54. The polyethylene of the connector 56 and the tubes 36 and 54 may be subsequently cross-linked to form cross-linked polyethylene (PEX). In a further illustrative embodiment, the hot water outlet tube 54 is simultaneously molded as part of the connector 56.
The cold water coupler 52 is substantially similar to the hot water coupler 50 as including the cold water supply tube 38 and a cold water outlet tube 58. A connector 60 fluidly couples the cold water supply tube 38 and the cold water outlet tube 58 through the cold water control valve cartridge 20. More particularly, the connector 60 fluidly couples the cold water supply tube 38 to the inlet of the valve cartridge 20, and fluidly couples the outlet of the valve cartridge 20 to the cold water outlet tube 58. Operation of the valve cartridge 20 controls the flow rate of cold water from supply tube 38 to outlet tube 58. Illustratively, the cold water supply tube 38 and the cold water outlet tube 58 are formed of a polymer, such as polyethylene, and the connector 60 is an overmold formed of a polymer, such as polyethylene, molded around the proximal ends of the tubes 38 and 58. The polyethylene of the connector 60 and the tubes 38 and 58 may be subsequently cross-linked to form cross-linked polyethylene (PEX). In a further illustrative embodiment, the cold water outlet tube 58 is simultaneously molded as part of the connector 60.
As further detailed herein, the couplers 50 and 52 illustratively include connectors 56 and 60 formed of a flowable material which are overmolded around proximal ends of supply tubes 36 and 38, respectively. While any suitable material may be used to form connectors 56 and 60, a polymer, including thermoplastics and thermosets, may be utilized in the illustrative embodiment. In one illustrative embodiment, the connectors 56 and 60 are each formed of polyethylene which has been overmolded around the proximal ends of the supply tubes 36 and 38 and subsequently cross-linked to form PEX. It should be noted that in certain illustrative embodiments, reinforcing members, such as glass fibers, may be provided within the polyethylene of the connectors 56 and 60.
Both waterway supply tubes 36 and 38 are flexible such that connecting distal ends 62 and 64 may be moved relative to opposing proximal ends coupled to the respective connectors 56 and 60. Illustratively, the tubes 36 and 38 are formed of a polymer, such as an olefin or a polyethylene. In one illustrative embodiment, the tubes 36 and 38 are formed of a polyethylene which has been cross-linked to form a cross-linked polyethylene (PEX). However, it should be appreciated that other suitable materials may be substituted therefor.
End fittings 66 and 68 are coupled to connecting ends 62 and 64, respectively, to facilitate coupling to conventional hot and cold water stops 19 and 21. Each end fitting 66, 68 illustratively includes a male adapter 70 and a coupling nut 72. In one illustrative embodiment, the end fittings 66 and 68 may be of the type detailed in U.S. patent application Ser. No. 12/233,839, filed Sep. 19, 2008, entitled “Overmolded Fitting Connection with Color Indication.”
The hot water outlet tube 54 of coupler 50 and the cold water outlet tube 58 of coupler 52 are fluidly coupled to an outlet member 74. More particularly, the outlet member 74 includes receiving bores 76 and 78 fluidly coupled to the outlet tubes 54 and 58. O-rings 79 provide seals between the outlet tubes 54 and 58 and receiving bores 76 and 78, respectively, of the outlet member 74. As with the connectors 56 and 60, the outlet member 74 may be formed of a polymer, such as cross-linked polyethylene (PEX).
In further illustrative embodiments, the waterway 22 may be formed such that the hot water coupler 50, the cold water coupler 52, and the outlet member 74 are integral with each other. In one illustrative embodiment, the outlet member 74 may be overmolded around the outlet tubes 54 and 58. More particularly, the outlet member 74 may be formed of a polymer, illustratively polyethylene, which has been overmolded around the ends of the outlet tubes 54 and 58 prior to cross-linking. The assembly of couplers 50 and 52 and outlet member 74 are then subsequently cross-linked to form PEX. In another illustrative embodiment, the connectors 56 and 60 of couplers 50 and 52 and outlet member 74 may be concurrently formed by molding around proximal ends of tubes 36 and 38. The connectors 56 and 60 and outlet member 74 may be formed of a polymer, illustratively polyethylene, which has been overmolded around the proximal ends of tubes 36 and 38 and then subsequently cross-linked to form PEX. Additional details of such an illustrative waterway are disclosed in International Patent Application Serial No. PCT/US09/40207 filed Apr. 10, 2009, entitled “Molded Waterway for a Two Handle Faucet.”
As noted above, the hot water valve cartridge 18 is fluidly coupled to the hot water supply conduit 36, while the cold water valve cartridge 20 is fluidly coupled to the cold water inlet conduit 38. More particularly, the hot water coupler or molded waterway 50 fluidly couples the hot water supply conduit 36 to the hot water valve cartridge 18 through an interface or base 80. Similarly, the cold water coupler or molded waterway 52 fluidly couples the cold water valve cartridge 20 to the cold water supply conduit 38 through an interface or base 81.
