Abstract

The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

First claim

Thus, having described the invention, what is claimed is:

1. A filter cartridge comprising:
a filter media having a longitudinal axial center; and
a filter cap securably attached to said filter media, said filter cap having a top surface including at least one identifying groove, rib, extended shape, or embedded shape, or any combination thereof, formed on, or attached to, said filter cap top surface, said filter cap including:
two cylindrical posts forming an ingress and egress port respectively, each post having an aperture presented on an outward facing sidewall in opposing directions for water ingress or egress into said post, each aperture providing for water flow in a direction horizontal to said longitudinal axial center, each post having a sealed top surface for preventing water flow in an axial direction through said post sealed top surface, an upper circumferential groove or rib above said aperture, and a lower circumferential groove or rib below said aperture, for securing a resilient water-tight seal above and below said port aperture to prevent axial flow of water on said outward facing sidewall above said upper circumferential groove or rib and below said lower circumferential groove or rib, and one of said posts being aligned in the axial center of said filter cartridge along said longitudinal axial center;

wherein a filter lid having a bottom complementary rib, groove, embedded shape, or extended shape, or any combination complementary to said filter cap top surface, adjoins said top surface of said filter cap by mating said at least one rib, groove, extended shape, or embedded shape from said filter lid bottom surface to said filter cap top surface, and securing said filter lid to said filter cap top surface by a clamp prior to attachment to a manifold.

2. The filter cartridge of claim 1 including a resilient filter cartridge enclosure encompassing said filter media in a water-tight seal, and insertable within a sump.

3. The filter cartridge of claim 1 including a resilient filter cartridge enclosure encompassing said filter media, and insertable within a sump includes, said filter cartridge enclosure including at least one aperture to provide for permeability and depressurization.

4. The filter cartridge of claim 2 wherein said resilient filter cartridge enclosure is secured to said filter cap.

5. The filter cartridge of claim 1 wherein said posts include resilient O-ring seals above and below each aperture.

6. A filter cartridge assembly comprising:
a sump adapted for sustaining pressure;
a filter media insertable within said sump;
a filter cap securably attached to said filter media, said filter cap having a top surface including at least one identifying groove, rib, extended shape, or embedded shape, or any combination thereof, formed on, or attached to, said filter cap top surface, said filter cap including:
two cylindrical posts forming an ingress and egress port respectively, each post having an aperture presented on an outward facing sidewall in opposing directions for water ingress or egress into said post, each aperture providing for water flow in a direction horizontal to said longitudinal axial center, each post having a sealed top surface for preventing water flow in an axial direction through said post sealed top surface, an upper circumferential groove or rib above said aperture, and a lower circumferential groove or rib below said aperture, for securing a resilient water-tight seal above and below said aperture to prevent axial flow of water on said outward facing sidewall above said upper circumferential groove or rib and below said lower circumferential groove or rib, and one of said posts being aligned in the axial center of said filter cartridge along said longitudinal axial center;
a filter lid having a bottom complementary rib, groove, embedded shape, or extended shape, or any combination complementary to said filter cap top surface, adjoining said top surface of said filter cap by mating said at least one rib, groove, extended shape, or embedded shape from said filter lid bottom surface to said filter cap top surface; and
a clamp for securing said sump to said filter lid prior to attachment to a manifold, said clamp circumferentially surrounding said filter lid and said sump.

7. The filter cartridge assembly of claim 6 wherein said clamp is a hoop strap.

8. The filter cartridge of claim 6 including a resilient filter cartridge enclosure encompassing said filter media and secured to said filter cap.

9. The filter cartridge of claim 8 wherein said resilient filter cartridge enclosure includes at least one aperture.

10. The filter cartridge of claim 6 wherein said posts include resilient O-ring seals above and below each aperture.

11. The filter cartridge of claim 6 including at least one boss on said sump for securing said sump to said manifold.
