Abstract

Air cleaner assemblies are described and shown. A serviceable filter cartridge is positioned within a housing. A unique axial projection arrangement is positioned on the cartridge, and it can be used as part of a projection/receiver arrangement.

First claim

What is claimed is:

1. An air filter cartridge comprising:
(a) media surrounding an open interior and having first and second, opposite, ends;
(b) first and second, opposite end caps including: an end cap positioned on the media first end; and, an end cap positioned on the second end of the media; and,
(i) the end cap on the first end of the media being an open end cap;
(ii) the end cap on the second end of the media being a closed end cap; and,

(c) an axial projection arrangement positioned on one of the end caps and projecting away from an opposite one of the end caps;
(i) the projection arrangement being positioned on the end cap that is on the second end of the media;
(ii) the projection arrangement extends around an interior space and includes a surface comprising a plurality of spaced, radially directed, convex sections.

2. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes a surface comprising a plurality of alternating radially directed convex and concave sections.

3. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes an outer surface comprising a plurality of radially directed convex sections.

4. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes an outer surface comprising a plurality of alternating radially directed convex and concave sections.

5. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement has an inner surface comprising a plurality of convex sections.

6. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement has an inner surface comprising a plurality of alternating radially directed convex and concave sections.

7. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes a surface comprising at least five each of alternating concave and convex sections, around a center.

8. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes a surface comprising 6-10 concave sections and 6-10 convex sections, around a center.

9. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes:
(i) an outer surface comprising at least five each of alternating concave and convex sections, around a center.

10. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes an outer surface comprising at least 6-10 each of alternating concave and convex sections, around a center.

11. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement includes:
(i) an outer surface comprising 6-10 concave sections and 6-10 convex sections, around a center; and,
(ii) an inner surface comprising 6-10 concave sections and 6-10 convex sections around a center.

12. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement comprises a projection with an inside surface having a smallest inside dimension thereacross of at least 15 mm.

13. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement comprises a projection with an inside surface having a smallest inside dimension thereacross of at least 20 mm.

14. An air filter cartridge according to claim 1 wherein:
(a) the projection arrangement comprises a projection with an inside surface having a smallest inside dimension thereacross within the range of 30-90 mm.

15. An air filter cartridge according to claim 1 wherein:
(a) the projection has an end tip; and,
(b) adjacent the end tip the projection has inner and outer surfaces;
(i) a thickness of the projection, in a direction between the inner and outer surfaces, not exceeding 10 mm in at least a portion of the projection.

16. An air filter cartridge according to claim 1 including:
(a) a radially inwardly directed housing seal arrangement.

17. An air filter cartridge according to claim 1 including:
(a) a radially outwardly directed housing seal arrangement.

18. An air filter cartridge according to claim 1 wherein:
(a) the housing seal arrangement comprises molded-in-place foamed polyurethane.

19. An air filter cartridge according to claim 1 wherein:
(a) the media is pleated.

20. An air filter cartridge according to claim 1 wherein:
(a) the media is cylindrical.

21. An air filter cartridge according to claim 1 wherein:
(a) the media has a conical taper.

22. An air filter cartridge comprising:
(a) media surrounding an open interior and having first and second, opposite, ends;
(b) first and second, opposite end caps including: an end cap positioned on the media first end; and, an end cap positioned on the second end of the media; and,
(c) an axial projection arrangement positioned on one of the end caps and projecting away from an opposite one of the end caps;
(i) the projection arrangement extending around an interior space and including a surface comprising a plurality of spaced, radially directed, convex sections;

(d) the end cap on the first end of the media being an open end cap;
(e) the end cap on the second end of the media being a closed end cap; and,
(f) the end cap on the second end of the media including a plurality of spaced adapter projections thereon positioned adjacent an outer perimeter.

23. An air filter cartridge according to claim 22 wherein:
(a) the adapter projections each project a distance of at least 10 mm away from an adjacent portion of the second end cap in a direction away from the first end cap.

24. An air filter cartridge according to claim 22 wherein:
(a) the second end cap includes eight spaced adapter projections.
