Abstract

A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

First claim

What is claimed is:

1. A filtration assembly, the filtration assembly comprising:
a housing comprising a first housing opening and a second housing opening; and
a containment cover removably coupled to the housing, the containment cover defining a cover opening that is in fluid communication with the housing, a cover surface, a flow passage, and an annular passage,
the cover surface substantially continuous around a circumference of the containment cover and comprising an open portion in fluid communication with the second housing opening,
the annular passage substantially continuous around a circumference of the containment cover, and
the flow passage formed by a first passage surface and a second passage surface, the flow passage comprising a first end in fluid communication with the cover opening and a second end in fluid communication with the second housing opening and the annular passage through the open portion of the cover surface, the flow passage extending radially outward from the cover opening.

2. The filtration assembly of claim 1 , wherein the cover surface comprises a first cover surface and the annular passage is formed by the first cover surface and a second cover surface, the second cover surface spaced inward from the first cover surface, wherein the flow passage is in fluid communication with the second housing opening by passing through the annular passage.

3. The filtration assembly of claim 2 , wherein the flow passage comprises a first flow passage, the containment cover further comprising:
a second flow passage formed by a third passage surface and a fourth passage surface, the second flow passage extending radially outward from the cover opening in a direction opposite from the first flow passage, the second flow passage comprising a third end and fourth end, the third end in fluid communication with the cover opening and the second end in fluid communication with the second housing opening by passing through the annular passage,
wherein the first flow passage and second flow passage define a diameter of the second cover surface.

4. The filtration assembly of claim 3 , wherein the first passage surface is substantially parallel to the second passage surface and the third passage surface is substantially parallel to the fourth passage surface, and wherein the first flow passage and the second flow passage extend in a direction that is substantially parallel to a face of the second housing opening.

5. The filtration assembly of claim 3 , wherein the first passage surface is substantially parallel to the second passage surface and the third passage surface is substantially parallel to the fourth passage surface, and wherein the first flow passage and the second flow passage extend in a direction that is substantially perpendicular to a face of the second housing opening.

6. The filtration assembly of claim 1 , wherein the first passage surface and second passage surface are adjacent to edges of the open portion.

7. The filtration assembly of claim 2 , wherein the first passage surface is tapered with respect to the second passage surface at a non-perpendicular draft angle, the draft angle defining the flow passage, the flow passage being in fluid communication with the second housing opening by passing through the annular passage, wherein each of the first passage surface and second passage surface define a radius of the second cover surface.

8. The filtration assembly of claim 7 , wherein the draft angle is structured to have the first passage surface and the second passage surface align with the open portion of the first cover surface.

9. The filtration assembly of claim 7 , wherein the first passage surface includes a flared gap extending in a counterclockwise direction, the flared gap facilitating fluid flow counterclockwise around the annular passage toward the second housing opening.

10. The filtration assembly of claim 2 , wherein the second cover surface is formed by an inner surface on the housing when the containment cover is installed with the housing.

11. The filtration assembly of claim 1 , wherein the first passage surface is tapered with respect to the second passage surface at a non-perpendicular draft angle, the draft angle defining the flow passage.

12. The filtration assembly of claim 1 , wherein the flow passage extends in a direction that is substantially perpendicular to a face of the second housing opening and the first passage surface is substantially parallel to the second passage surface, and wherein the first passage surface and second passage surface comprise outside edges of the open portion.

13. The filtration assembly of claim 1 , wherein the flow passage extends in a direction that is substantially perpendicular to a face of the second housing opening and the first passage surface is substantially parallel to the second passage surface, and wherein the first passage surface and second passage surface comprise inside edges of the open portion.

14. The filtration assembly of claim 1 , wherein first housing opening is a fluid inlet for fluid to be filtered and the second housing opening is a fluid outlet for filtered fluid, and wherein the flow passage comprises a biasing member on the second end, the biasing member configured to bias the filtered fluid toward the second housing opening.

15. The filtration assembly of claim 14 , wherein first housing opening is a fluid inlet for fluid to be filtered and the second housing opening is a fluid outlet for filtered fluid, and wherein the biasing member comprises a curved indentation on the second end of the flow passage, the curved indentation angled so as to bias the filtered fluid toward the second housing opening.

16. The filtration assembly of claim 14 , wherein the biasing member comprises a v-shaped protrusion on the second end of the flow passage, the v-shaped protrusion configured to facilitate filtered fluid out of the flow passage and into the second housing opening.

17. The filtration assembly of claim 1 , wherein the first passage surface is tapered with respect to the second passage surface at a non-perpendicular draft angle, the draft angle defining the flow passage, the flow passage being in direct fluid communication with the second housing opening by passing through the open portion of the cover surface, wherein each of the first passage surface and second passage surface define a radius of the cover surface.

18. A filtration assembly, the filtration assembly comprising:
a housing comprising a first housing opening and a second housing opening;
a fluid filter element removably installed within the housing, the fluid filter element comprising filtration media comprising a filtered fluid side, an unfiltered fluid side, and a center compartment; and
a containment cover removably coupled to the housing, the containment cover defining a cover opening in fluid communication with the center compartment of the filtration media, a cover surface, a flow passage, and an annular passage,
the cover surface substantially continuous around a circumference of the containment cover and comprising an open portion in fluid communication with the second housing opening of the housing,
the annular passage substantially continuous around a circumference of the containment cover, and
the flow passage formed by a first passage surface and a second passage surface, the flow passage comprising a first end in fluid communication with the cover opening and a second end in fluid communication with the second housing opening and the annular passage through the open portion of
