Abstract

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

First claim

What is claimed:

1. An air filter cartridge comprising:
(a) a media pack comprising filter media and having first and second, opposite, flow ends;
(i) the first flow end comprising an inlet flow end;
(ii) the second flow end comprising an outlet flow end; and,
(iii) the media pack being configured to filter air flowing into the inlet flow end prior to the air exiting the outlet flow end; and,

(b) a housing seal arrangement positioned on the media pack;
(i) the housing seal arrangement defining an air flow passageway;
(ii) the housing seal arrangement comprising a first radially outwardly directed, seal member defining a first radial seal surface oriented to releasably, sealingly engage surrounding structure, in use;
(iii) the first radial seal surface defining a perimeter-direction in extension around the flow passageway; and,
(iv) the first radial seal surface including:
(A) at least a first seal surface section including a radially directed portion comprising an alternating radial projection/recess configuration comprising at least two projections and three recesses in extension along a portion of the perimeter-direction; and,
(B) at least 30% of extension of the radial seal surface, in the perimeter-direction, not comprising an alternating projection/recess configuration and having no recesses therein.

2. An air filter cartridge according to claim 1 wherein:
(a) the first radial seal surface includes at least a first seal surface section and second seal surface section, in extension in the perimeter-direction, each including a radially directed portion comprising an alternating projection/recess configuration.

3. An air filter cartridge according to claim 1 wherein:
(a) at least 40% of an extension of the first radial seal surface, in a perimeter-direction, not comprising an alternating projection/recess configuration and having no recesses therein.

4. An air filter cartridge according to claim 1 wherein:
(a) the first radial seal surface includes a perimeter direction shape having: two, opposite, straight seal surface sections and two, opposite, arcuate seal surface sections;
(i) the straight seal surface sections extending between the arcuate seal surface sections.

5. An air filter cartridge according to claim 4 wherein:
(a) each one of the two, opposite, arcuate seal sections has an alternating projection/recess configuration having at least two projections and three recesses in extension along a portion of the perimeter-direction.

6. An air filter cartridge according to claim 5 wherein:
(a) each one of the two, opposite, arcuate seal sections comprises first and second end projections; and, first and second end recesses;
(i) each end projection being spaced from an adjacent one of the two opposite straight sections by at least an adjacent one of the end recesses.

7. An air filter cartridge according to claim 6 wherein:
(a) each one of the two, opposite, arcuate seal sections includes an associated intermediate recess adjacent each end projection on an opposite side thereof from an adjacent one of the end recesses;
(i) each associated intermediate recess having a greater depth of extension in a direction away from an outer most portion of the projection than does each next adjacent end recess.

8. An air filter cartridge according to claim 1 wherein:
(a) the first radial seal surface comprises:
(i) a portion defining a hypothetical standard shape seal surface engagement perimeter co-linear with at least one non-projection/recess seal section of the first radial seal surface; and,
(ii) at least a first projection/recess seal surface section including a radially directed portion comprising a first surface definition with an installation interference projection arrangement that extends, in a sealing direction, from the hypothetical standard shape seal surface engagement perimeter.

9. An air filter cartridge according to claim 1 wherein:
(a) the first radial seal surface has a portion defining a hypothetical standard shape seal surface engagement perimeter co-linear with at least one non-projection/recess seal section of the first radial seal surface; and,
(b) the first radial seal surface includes at least a first projection/recess seal surface section including a radially directed portion comprising a first surface definition with at least a first seal surface portion that extends in a direction across the hypothetical standard shape seal surface engagement perimeter.

10. An air filter cartridge according to claim 1 wherein:
(a) the media pack has an oval cross-sectional shape in extension between the first and second, opposite inlet and outlet, flow ends;
(i) the oval cross-sectional shape defining first and second curved ends with sides extending in a therebetween;

(b) the housing seal arrangement is positioned at the outlet flow end; and,
(c) a handle arrangement is positioned on a preform adjacent the inlet flow end with a handle member in overlap with one of the first and second curved ends.

11. An air filter cartridge according to claim 1 wherein:
(a) the cartridge includes a seal support therein embedded within seal material of the housing seal arrangement.

12. An air filter cartridge according to claim 11 wherein:
(a) the seal support includes at least one wide recess on each side of a narrow projection tip.

13. An air filter cartridge according to claim 1 wherein:
(a) at least one projection in the first radial seal surface is a segmented projection.

14. An air filter cartridge according to claim 1 wherein:
(a) at least one recess in the first radial seal surface is a segmented recess.

15. An air filter cartridge according to claim 1 wherein:
(a) at least one projection in the first radial seal surface is a truncated projection.

16. An air filter cartridge according to claim 1 wherein:
(a) at least one recess in the first radial seal surface includes a portion bowed in a direction of a projection.

17. An air filter cartridge according to claim 1 wherein:
(a) the first radial seal surface includes at least 30% of extension, in the perimeter-direction: not comprising an alternating projection/recess configuration, not having a recess therein; and, having a perimeter-direction shape corresponding to a circular arc definition.

18. An air filter cartridge according to claim 1 wherein:
(a) the housing seal arrangement includes a first seal surface portion having a section of wavy shape comprising an alternating projection/recess configuration with:
(i) a contoured first perimeter-direction length L 1 ; and,
(ii) a corresponding non-contoured first perimeter-direction length L 2 ;
(A) wherein a ration of L 1 /L 2 is at least 1.01.

19. An air filter cartridge according to claim 1 wherein:
(a) the housing seal arrangement includes a second radial seal surface portion oriented to releasably, sealingly, engage on an air cleaner in use;
(i) the second radial seal surface portion being in axial alignment with the first radially directed portion; and,
(ii) the second radial seal surface portion being configured to sealingly engage a non-projection/recess seal surface of a housing.

20. An air cleaner assembly comprising:
(a) a housing including a body and access cover;
(i) the housing includes a structural seal surface including a wavy section for sealing there against of a cartridge seal;

(b) an air filter cartridge is accord with claim 1 positioned within the housing and releasably sealed to the structura
