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 manifold for a filtration system comprising:
a valve including a first and second aperture on a left side of said manifold, and a corresponding first and second aperture on a right side of said manifold, said first and second apertures on said manifold left side adjacent one another, and said first and second apertures on said manifold right side adjacent one another, at least a portion of said first aperture on said manifold left positioned vertically higher than said second aperture on said manifold left side, at least a portion of said first aperture on said manifold right side positioned vertically higher than said second aperture on said manifold right side, such that said first apertures are in fluid communication with a mounting bracket left and right fluid ports when said manifold is pivoted to a first position, and said second apertures are in fluid communication with said mounting bracket left and right fluid ports when said manifold is pivoted to said second position; and
at least one pivot to provide pivotable rotation for said manifold with respect to said mounting bracket.

2. The manifold of claim 1 including a circumferential resilient seal about said first and second apertures on said manifold left, and a circumferential resilient seal about said first and second apertures on said manifold right side.

3. The manifold of claim 2 wherein said adjacent first and second apertures comprise a kidney-shaped outer boundary.

4. The manifold of claim 1 wherein said pivot includes at least one pivot boss or pivot boss receiver on said manifold in rotational contact with at least one complementary pivot boss receiver or pivot boss on said mounting bracket.

5. The manifold of claim 1 wherein said pivot includes at least one pivot pin or aperture to receive a pivot pin on said manifold in rotational contact with at least one complementary aperture or pivot pin on said mounting bracket.

6. The manifold of claim 1 having a manifold bottom surface including a plurality of ribs or grooves for mating with a plurality of complementary grooves or ribs embedded within a filter lid top surface.

7. A manifold-mounting bracket combination for securing a filter cartridge assembly, said combination comprising:
said manifold including:
a valve including a first and second aperture on a left side of said manifold, and a corresponding first and second aperture on a right side of said manifold, said first and second apertures on said manifold left side adjacent one another, and said first and second apertures on said manifold right side adjacent one another, at least a portion of said first aperture on said manifold left positioned vertically higher than said second aperture on said manifold left side, at least a portion of said first aperture on said manifold right side positioned vertically higher than said second aperture on said manifold right side, such that said first apertures are in fluid communication with a mounting bracket left and right fluid ports when said manifold is pivoted to a first position, and said second apertures are in fluid communication with said mounting bracket left and right fluid ports when said manifold is pivoted to said second position;
at least one pivot boss or pivot boss receiver; and
at least one shoulder bolt or guide track; and
said mounting bracket including:
at least one pivot boss receiver or pivot boss in rotational contact with said at least one complementary pivot boss or pivot boss receiver on said manifold to provide pivotable rotation for said manifold;
at least one guide track or shoulder bolt in slidable contact with said at least one complementary shoulder bolt or guide track on said manifold for slidably mating said manifold to said mounting bracket, said at least one guide track guiding said manifold pivoting from said first position to said second position.
