Abstract

A filtration sealing system is provided for sealing a filter element in a housing at a mating interface therebetween. The sealing system includes a keyed interface. A replacement filter element is provided for such filtration sealing system, with the replacement filter element including a keyed interface.

First claim

What is claimed is:

1. A filtration sealing system, the system comprising:
a first housing section having a border therearound;
a second housing section having a border therearound:
a filter element between the first and second housing sections and having a border therearound; and
a gasket extending in an x-y plane and providing a mating interface between the border around the filter element the borders around the first and second housing sections, a first side of the gasket engaging an entire periphery of the border around the first housing section and a second, opposite side of the gasket engaging an entire periphery of the border around the second housing section, at least one of the first side and the second side of the gasket having one or more humped arches humped in a z-direction that is perpendicular to the x-y plane;
wherein one of the border around the first housing section, the border around the second housing section, and the border around the filter element has one or more concave recessed slits recessed in the z-direction and complementary receiving the humped arches therein; and
wherein the gasket is sealed along the entire mating interface, including being sealed at all of the humped arches and all of the concave recessed slits, and blocks fluid flow across the gasket, including, blocking fluid flow across the humped arches and blocking fluid flow across the concave recessed slits.

2. The filtration sealing system of claim 1 , wherein the gasket and at least one of the border around the first housing section, the border around the second housing section, and the border around the filter element engage each other in detent relation so as to form a keyed mating interface.

3. The filtration sealing system of claim 1 , wherein the gasket extends along an extension direction along a perimeter.

4. The filtration sealing system of claim 3 , wherein the first side of the gasket lies flat on the x-y plane along the entire perimeter and the second side of the gasket has the one or more humped arches.

5. The filtration sealing system of claim 4 , wherein more than one humped arch is provided and wherein between the humped arches, the second side of the gasket lies flat on a plane that is parallel to the x-y plane.

6. The filtration sealing system of claim 5 , wherein the humped arches are spaced along the perimeter.

7. The filtration sealing system of claim 6 , wherein the humped arches are spaced at regular intervals along the perimeter.

8. The filtration sealing system of claim 3 , wherein the one or more humped arches extend transversely to the extension direction.

9. The filtration sealing, system of claim 8 , wherein the one or more humped arches have a longer dimension transverse to the extension direction than a dimension in the extension direction.

10. The filtration sealing system of claim 3 , wherein the gasket is separate from the border around the filter element.

11. The filtration sealing system of claim 3 , wherein the gasket is molded to and integral with the border around the filter element and the one or more concave recessed slits are in one of the border around the first housing section and the border around the second housing section.

12. The filtration sealing system of claim 11 , wherein one or more of a size, shape, and spacing of the one or more humped arches and the one or more concave recessed slits prevents replacement of the filter element with a filter element that has humped arches that are not complementary received by the concave recessed slits.

13. The filtration sealing system of claim 11 , wherein one or more of a size, shape, and spacing of the one or more humped arches and the one or more concave recessed slits prevents replacement of the filter element in an orientation in Which the one or more humped arches are not complementary received by the one or more concave recessed slits.

14. A filter element for a filtration sealing system, the filter element comprising:
a filter media;
a border that extends around the filter media for mating with a border of a housing in which the filter element is received; and
a gasket extending in an x-y plane and providing a mating interface between the border of the filter element and the border of the housing, the gasket having a first side and a second, opposite side, at least one of the first side and the second side of the gasket having one or more humped arches humped in a z-direction that is perpendicular to the x-y plane;
wherein one of the border of the housing and the border of the filter element has one or more concave recessed slits recessed in the z-direction for complementary receiving the humped arches therein such that the filter element can only be received in the housing when the humped arches are aligned with and fit into the concave recessed slits; and
wherein when the gasket, filter element, and housing, are assembled to one another, the gasket provides a seal along the entire mating interface, including providing a seal at all of the humped arches and all of the concave recessed slits, and blocks fluid flow across the gasket, including blocking fluid flow across all of the humped arches and blocking fluid flow across all of the concave recessed slits.

15. The filter element of claim 14 , wherein the gasket extends along an extension direction along a perimeter.

16. The filter element of claim 15 , wherein the first side of the gasket lies flat on the plane along the entire perimeter and the second side of the gasket has the one or more humped arches.

17. The filter element of claim 16 , wherein the one or more humped arches extend transversely to the extension direction.

18. The filter element of claim 17 , wherein the one or more humped arches have a longer dimension transverse to the extension direction than a dimension in the extension direction.

19. The filter element of claim 14 , wherein the gasket is molded to and integral with the border of the filter element and the one or more concave recessed slits are in the border of the housing.

20. A filtration sealing system for sealing a filter element in a housing at a mating interface therebetween, the sealing system comprising a keyed interface, wherein:
the filter element and the housing have borders mating with each other at a gasket therebetween and providing the mating interface
the gasket and at least one of the housing and the filter element engage each other in detent relation providing the keyed interface;
the gasket extends along an extension direction along a perimeter;
the gasket has a first side and a second, opposite side;
the first side of the gasket lies flat on a plane extending in an x-direction and a y-direction that is perpendicular to the x-direction;
the second side of the gasket has one or more humped arches spaced along the perimeter and humped in a z-direction that is perpendicular to the x-direction and to the y-direction;
the one or more humped arches extend transversely to the extension direction and have a longer dimension transverse to the extension direction than a dimension in the extension direction:
the at least one of the housing and the filter element has one or more concave recessed slits spaced along its respective border and recessed in the z-direction and complementary receiving the one or more humped arches therein such that the filter element can only be received in the housing when the one or more humped arches are aligned with and fit into the one or more concave recessed slits;
a fluid to be filtered flows through
