Abstract

A filter element assembly includes a filter body and an auxiliary filter. The filter body includes a sidewall around a hollow core. Further the filter body and auxiliary filter are both received and held on a support including a base and a cage.

First claim

What is claimed:

1. An filter element assembly for a motor vehicle comprising:
a support;
a filter body carried on said support, said filter body including a sidewall around a hollow core; and
an auxiliary filter carried directly on said support against said sidewall.

2. The filter element assembly of claim 1 , wherein said filter body forms an elliptic cylinder.

3. The filter element assembly of claim 2 , wherein a first end of said core is closed by said support and a second end of said core is an axial outlet.

4. The filter element assembly of claim 3 , wherein said filter body is a pleat-pack filter.

5. The filter element assembly of claim 4 , wherein said auxiliary filter is an open cell foam.

6. The filter element assembly of claim 5 , wherein said auxiliary filter is carried on said support outside said core.

7. The filter element assembly of claim 6 , wherein said filter body has a first longitudinal axis and said auxiliary filter has a second longitudinal axis wherein said first longitudinal axis is parallel to and offset from said second longitudinal axis.

8. The filter element assembly of claim 7 , further including a sealing ring on said filter body around said axial outlet.

9. The filter element assembly of claim 1 , wherein a first end of said core is closed by said support and a second end of said core is an axial outlet.

10. The filter element assembly of claim 1 , wherein said filter body is a pleat-pack filter.

11. The filter element assembly of claim 1 , wherein said auxiliary filter is an open cell foam.

12. The filter element assembly of claim 1 , wherein said auxiliary filter is carried on said support outside said core.

13. The filter element assembly of claim 1 , wherein said filter body has a first longitudinal axis and said auxiliary filter has a second longitudinal axis wherein said first longitudinal axis is parallel to and offset from said second longitudinal axis.

14. The filter element assembly of claim 1 , further including a sealing ring on said filter body around said axial outlet.

15. The filter element assembly of claim 1 , including an adhesive for securing said auxiliary filter to said support.

16. The filter assembly of claim 15 , including an adhesive for security said auxiliary filter to said sidewall.

17. The filter element assembly of claim 16 wherein said adhesive is provided on peaks of two outermost pleats which engage said auxiliary filter in order to secure said auxiliary filter in place.

18. The filter element assembly of claim 1 wherein said support includes at least one mounting cup.
