Fluid delivery assembly (2-in and 1-out, plus quick-connect diverter housing assembly)
The invention provides a fluid delivery assembly for use with a water discharge fixture, such as a faucet. The fluid delivery assembly includes a tube assembly, a housing and a retaining assembly. The fluid delivery assembly provides for water flow from hot and cold water inlets to the faucet. The fluid delivery assembly may be assembled by hand without the need for tools, allowing for easy replacement of the fluid delivery assembly, without the need to disassemble the faucet assembly or to replace the entire faucet assembly.
1. A fluid delivery assembly for use with a first fluid discharge fixture, the fluid delivery assembly comprising:
a housing comprising at least one fluid inlet and at least one fluid outlet;
at least one tube assembly defining at least one fluid flow path, wherein a first portion of the tube assembly is configured to connect to a fluid source line, and wherein a second portion of the tube assembly is configured to connect to the housing;
wherein the tube assembly comprises:
a first tube defining a fluid pathway from a first fluid source to the housing;
a second tube defining a fluid pathway from a second fluid source to the housing; and
a third tube defining a fluid pathway from the housing to a second fluid discharge fixture, wherein a portion of the first tube and a portion of the second tube are molded together to form a molded junction portion, and wherein the molded junction portion comprises a receiving channel configured to slidably receive the third tube;
and
a retaining assembly to secure the tube assembly and the housing, wherein the retaining assembly is configured to be engaged or disengaged by hand without the use of tools, and wherein the housing, the tube assembly, and the retaining assembly are separate components that are not integrally formed together.
2. The fluid delivery assembly of claim 1 , further comprising a cartridge housing configured to receive a fluid flow cartridge.
3. The fluid delivery assembly of claim 1 , wherein the tube assembly is comprised of PERT plastic tubing and the housing is comprised of plastic.
4. The fluid delivery assembly of claim 2 , wherein the retaining assembly comprises:
a mounting member sized and shaped to receive a portion of the housing, wherein a portion of the mounting member is threaded; and
a securing member, wherein a portion of the securing member is threaded, and wherein the threaded portion of the mounting member is configured to cooperatively engage with the threaded portion of the securing member to secure the tube assembly to the housing.
5. The fluid delivery assembly of claim 4 , wherein the retaining member is a mounting shank comprised of metal, and wherein the securing member is a mounting nut comprised of metal.
6. The fluid delivery assembly of claim 5 , wherein a portion of the mounting shank is internally threaded and a portion of the mounting nut is externally threaded.
7. The fluid delivery assembly of claim 2 , wherein the tube assembly further comprises:
a fourth tube defining a fluid pathway from the housing to the first fluid discharge fixture
wherein the molded junction portion comprises an alignment member configured to receive the fourth tube.
8. The fluid delivery assembly of claim 7 , wherein a first fluid flows from an angle valve of the first fluid source, through the first tube into the housing, and into a fluid flow cartridge, wherein a second fluid flows from an angle valve of the second fluid source, through the second tube into the housing, and into a fluid flow cartridge, wherein the first and second fluids are mixed in the fluid flow cartridge and the mixed fluid flows through the housing to one of the delivery spout and a sprayer, wherein to reach both the delivery spout and the sprayer the mixed fluid flows from the fluid flow cartridge to the housing to the third tube to a diverter assembly.
