Abstract

A filter element, including: a first filter media body having a filter media and an inflow side and an outflow side; and a second filter media body having a filter media and an inflow side and an outflow side; wherein the first filter media body and the second filter media body are adapted for installation into a filter element housing shared by both filter media bodies; wherein the filter element has a longitudinal axis; wherein the filter media bodies in the filter element housing delimit a common clean chamber shared by both filter media bodies, the common clean chamber from which the cleaned fluid is to be discharged via at least one outflow aperture; wherein at least one of the filter media bodies is constructed from at least two sections, each section differing in size from other sections.

First claim

What is claimed is:

1. A filter element, comprising:
a first filter media body having a filter media and an inflow side and an outflow side; and
a second filter media body having a filter media and an inflow side and an outflow side;
wherein the first filter media body and the second filter media body are adapted for installation into a filter element housing shared by both filter media bodies;
wherein the filter element has a longitudinal axis;
wherein the filter media bodies in the filter element housing delimit a common clean chamber shared by both filter media bodies, the common clean chamber from which a cleaned fluid is to be discharged via at least one outflow aperture;
wherein at least one of the filter media bodies is constructed from at least two sections, each section differing in size from other sections;
wherein the sections differ in height orthogonal to flow direction of the filter media bodies.

2. The filter element according to claim 1 , wherein
the first and/or second filter media body comprises
two cuboidal sections of different sizes, which are connected via a ramp-shaped section.

3. The filter element according to claim 1 , wherein
the first and/or second filter media body comprises
two cuboidal sections between which a part-circular cut-out section is situated.

4. The filter element according to claim 1 , wherein
the first filter media body has at least one section which differs in size from the second filter media body.

5. The filter element according to claim 4 , wherein
all sections of the first filter media body in one expansion direction are smaller in size than similarly arranged sections of the second filter media body.

6. The filter element according to claim 1 , wherein
the outflow aperture has a central axis;
wherein the axis of the outflow aperture is disposed at least approximately coaxially or parallel to a longitudinal axis of the filter element.

7. The filter element according to claim 1 , wherein
the outflow aperture has a central axis;
wherein the axis of the outflow aperture is disposed at least approximately perpendicular to the longitudinal axis of the filter element.

8. The filter element according to claim 1 , wherein
the first filter media body and the second filter media body each are received into an outwardly open receiving pocket at the filter element housing.

9. The filter element according to claim 1 , wherein
the filter media of the filter media bodies are configured as pleated filters having pleated filter media;
wherein the sections of the filter media body have a different height, wherein the different heights of the sections of the filter media body is formed by different pleat widths.

10. The filter element according to claim 9 , wherein
the pleated filters are adhesively bonded at end edges.

11. The filter element according to claim 1 , wherein
the first filter media body and the second filter media body are substantially identical.

12. The filter element according to claim 1 , wherein
at least one edge in the filter element housing, which surrounds the inflow or the outflow side of a filter media body, is not formed in a straight manner.

13. The filter element according to claim 1 , wherein
the first filter media body is offset in at least one of: longitudinally, transversely, in height and/or an angular offset relative to the second filter media body.

14. The filter element according to claim 1 , wherein
the filter element housing is formed as a one-piece integrally formed plastic injection molding component.

15. A filter element, comprising:
a first filter media body having a filter media and an inflow side and an outflow side; and
a second filter media body having a filter media and an inflow side and an outflow side;
wherein the first filter media body and the second filter media body are adapted for installation into a filter element housing shared by both filter media bodies;
wherein the filter element has a longitudinal axis;
wherein the filter media bodies in the filter element housing delimit a common clean chamber shared by both filter media bodies, the common clean chamber from which a cleaned fluid is to be discharged via at least one outflow aperture;
wherein at least one of the filter media bodies is constructed from at least two sections, each section differing in size from other sections;
wherein the filter medium bodies have parallel inflow and outflow sides.

16. The filter element according to claim 15 , wherein
the first filter media body and the second filter media body each are received into an outwardly open receiving pocket at the filter element housing.

17. A filter device comprising:
a filter element including:
a first filter media body having a filter media and an inflow side and an outflow side; and
a second filter media body having a filter media and an inflow side and an outflow side;
wherein the first filter media body and the second filter media body are adapted for installation into a filter element housing shared by both filter media bodies;
wherein the filter element has a longitudinal axis;
wherein the filter media bodies in the filter element housing delimit a common clean chamber shared by both filter media bodies, the common clean chamber from which a cleaned fluid is to be discharged via at least one outflow aperture; and
wherein at least one of the filter media bodies is constructed from at least two sections, each section differing in size from other sections;
wherein the sections differ in height orthogonal to flow direction of the filter media bodies; and

a filter housing into which the filter element is received.
