Abstract

According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

First claim

What is claimed:

1. A filter cartridge comprising:
(a) first and second opposite flow ends, wherein one of the first and second opposite flow ends comprises an inlet and the other of the first and second opposite flow ends comprises an outlet;
(b) filter media positioned to filter fluid flow between the first and second opposite flow ends and having an outer periphery;
(c) a shell arrangement comprising:
(i) a shell body surrounding the outer periphery of the filter media and having a first end and a second end;
(ii) a first seal support extending from the shell body first end in a direction away from the filter media; and
(iii) a shell body filter media support extending from the shell body second end and supporting the filter media within the shell arrangement;

(d) a ring arrangement comprising:
(i) a ring body surrounding the outer periphery of the filter media and having a first end and second end;
(ii) a ring body filter media support extending from the ring body first end and supporting the filter media within the ring arrangement;
(iii) a second seal support extending from the ring body second end in a direction away from the filter media; and

(e) a seal member molded onto the first seal support and the second seal support and holding the first seal support and the second seal support together, and wherein the seal member includes a seal surface extending around the filter media and constructed to form a seal with a housing.

2. A filter cartridge according to claim 1 wherein:
(a) the media extends over a distance of at least 80 mm in a direction between the first and second flow ends.

3. A filter cartridge according to claim 1 wherein:
(a) the media extends over a distance of at least 150 mm in a direction between the first and second flow ends.

4. A filter cartridge according to claim 1 wherein:
(a) the media extends over a distance of at least 180 mm in a direction between the first and second flow ends.

5. A filter cartridge according to claim 1 wherein:
(a) the first seal support comprises a radially extending flange having a plurality of openings therein.

6. A filter cartridge according to claim 5 wherein:
(a) the first seal support comprises a funnel portion between the shell body and the radially extending flange, and the plurality of openings extend into the funnel portion.

7. A filter cartridge according to claim 5 wherein:
(a) the second seal support comprises a plurality of projections extending into the plurality of openings.

8. A filter cartridge according to claim 7 wherein:
(a) the seal member is provided extending through the plurality of openings and around the plurality of projections.

9. A filter cartridge according to claim 8 wherein:
(a) the seal member adheres the shell arrangement and the ring arrangement to the filter media.

10. A filter cartridge according to claim 1 wherein:
(a) the shell body filter media support extends from one side of the shell body second end to the other side of the shell body second end.

11. A filter cartridge according to claim 1 wherein:
(a) the ring body filter media support comprises a plurality of projections extending from an inside surface of the ring body and located above the filter media.

12. A filter cartridge according to claim 1 wherein:
(a) the shell body comprises and inner surface having recesses therein for receiving a fin arrangement.

13. A filter cartridge according to claim 12 further comprising:
(a) a fin arrangement provided extending from an inner surface of the ring body.

14. A filter cartridge according to claim 13 wherein:
(a) the fin arrangement includes two side members and a curved extension located between the two side members and provided for directing air.

15. A filter cartridge according to claim 1 wherein:
(a) the seal member has first and second, opposite, pinch surfaces, and one of the pinch surfaces comprises the seal surface extending around the filter media.

16. A filter cartridge according to claim 15 , wherein:
(a) the seal surface extending around the filter media comprises an axial sealing surface.

17. A filter cartridge according to claim 1 wherein:
(a) the seal surface extending around the filter media is located radially outward from both the shell body and the ring body.

18. A filter cartridge comprising:
(a) first and second opposite flow ends, wherein one of the first and second opposite flow ends comprises an inlet and the other of the first and second opposite flow ends comprises an outlet;
(b) filter media positioned to filter fluid flow between the first and second opposite flow ends and having an outer periphery;
(c) a shell arrangement comprising:
(i) a shell body surrounding the outer periphery of the filter media and having a first end and a second end;
(ii) a first seal support extending from the shell body first end in a direction away from the filter media and comprising a radially extending flange having a plurality of openings therein; and
(iii) a shell body filter media support extending from the shell body second end and supporting the filter media within the shell arrangement;

(d) a ring arrangement comprising:
(i) a ring body surrounding the outer periphery of the filter media and having a first end and second end;
(ii) a ring body filter media support extending from the ring body first end and supporting the filter media within the ring arrangement;
(iii) a second seal support extending from the ring body second end in a direction away from the filter media; and

(e) a seal member molded onto the first seal support and the second seal support and holding the first seal support and the second seal support together.

19. A filter cartridge according to claim 18 wherein:
(a) the first seal support comprises a funnel portion between the shell body and the radially extending flange, and the plurality of openings extend into the funnel portion.

20. A filter cartridge according to claim 18 wherein:
(a) the second seal support comprises a plurality of projections extending into the plurality of openings.

21. A filter cartridge according to claim 20 wherein:
