Claims
- 1. An adapter assembly for use in mating a filter cartridge to a filter manifold, comprising:
an adapter body having a manifold coupler and a cartridge coupler; the manifold coupler for mating with the filter manifold and having a manifold coupler inlet being fluidly communicable with a filter manifold fluid inlet and a fluid outlet and further being fluidly communicable with a filter manifold fluid outlet and having sealing means, the sealing means isolating an inlet flow of unfiltered water from an outlet flow of filtered water; and the cartridge coupler for mating with the filter cartridge and having a cartridge coupler fluid inlet, said inlet being fluidly communicable with a filter cartridge inlet and being in fluid communication with the manifold coupler inlet and having a cartridge coupler fluid outlet, said outlet being fluidly communicable with a filter cartridge outlet and being in fluid communication with the manifold coupler outlet and further having sealing means, the sealing means isolating an inlet flow of unfiltered water to the filter cartridge from an outlet flow of filtered water form the filter cartridge.
- 2. The adapter assembly of claim 1 further including at least a first pair of shoulders for compressive, retaining engagement with the filter manifold.
- 3. The adapter assembly of claim 2 further including at least a first pair of lugs for compressive, retaining engagement with the filter cartridge.
- 4. The adapter assembly of claim 1, at least one adapter assembly valve being disposed in the adapter body to control a flow of water therethrough.
- 5. The adapter assembly of claim 4 wherein the at least one adapter assembly valve has a fluted shaft, a plurality of flutes defined by the fluted shaft comprising a plurality of flow passages.
- 6. The adapter assembly of claim 5 wherein the at least one adapter assembly valve has an integral seal.
- 7. The adapter assembly of claim 6 wherein the at least one adapter assembly valve integral seal is formed by overmolding on a valve body.
- 8. The adapter assembly of claim 4 wherein mating the manifold coupler to the filter cartridge acts to open the at least one adapter assembly valve.
- 9. The adapter assembly of claim 1 wherein mating the manifold coupler to the filter manifold acts to open a valve disposed in the filter manifold.
- 10. The adapter assembly of claim 9 wherein the adapter body includes a margin, the margin bearing on the filter manifold valve during mating the manifold coupler to the filter manifold and thereby acting to open the filter manifold valve.
- 11. An adapter assembly for use in mating a filter cartridge to a filter manifold, comprising:
adapter body means for mating the filter cartridge to the filter manifold, the adapter body means having manifold coupler means and cartridge coupler means; the manifold coupler means for mating with the filter manifold and having a manifold coupler inlet, said inlet being fluidly communicable with a filter manifold fluid inlet and a fluid outlet being fluidly communicable with a filter manifold fluid outlet and further having sealing means, the sealing means for isolating an inlet flow of unfiltered water from an outlet flow of filtered water; and the cartridge coupler means for mating with the filter cartridge and having a cartridge coupler fluid inlet, said inlet being fluidly communicable with a filter cartridge inlet and being in fluid communication with the manifold coupler inlet and a cartridge coupler fluid outlet, said fluid outlet being fluidly communicable with a filter cartridge outlet and being in fluid communication with the manifold coupler outlet and further having sealing means, the sealing means isolating an inlet flow of unfiltered water to the filter cartridge from an outlet flow of filtered water from the filter cartridge.
- 12. The adapter assembly of claim 11 further including at least a first pair of shoulders for compressive, retaining engagement with the filter manifold.
- 13. The adapter assembly of claim 12 further including at least a first pair of lugs for compressive, retaining engagement with the filter cartridge.
- 14. The adapter assembly of claim 11, at least one adapter assembly valve being disposed in the adapter body to control a flow of water therethrough.
- 15. The adapter assembly of claim 14 wherein the at least one adapter assembly valve means has a fluted shaft, a plurality of flutes defined by the fluted shaft comprising a plurality of flow passages.
- 16. The adapter assembly of claim 15 wherein the at least one adapter assembly valve means has integral seal means.
- 17. The adapter assembly of claim 16 wherein the at least one adapter assembly valve means integral seal means is formed by overmolding on a valve body.
- 18. The adapter assembly of claim 11 wherein mating the manifold coupler means to the filter cartridge acts to open the at least one adapter assembly valve means.
- 19. The adapter assembly of claim 11 wherein mating the manifold coupler means to the filter manifold acts to open a valve disposed in the filter manifold.
- 20. The adapter assembly of claim 19 wherein the adapter body means includes a margin, the margin bearing on the filter manifold valve during mating the manifold coupler means to the filter manifold and thereby acting to open the filter manifold valve.
