Abstract

A filter element has a filter element housing with first and second outwardly open receiving pockets. A first filter medium body is disposed in the first receiving pocket. A second filter medium body is disposed in the second receiving pocket. The first and second filter medium bodies delimit a common clean chamber that communicates with an outflow opening for purified fluid. The first receiving pocket has a circumferential first support rim on which the first medium body is supported. The second receiving pocket has a circumferential second support rim on which the second filter medium body is supported. The first receiving pocket has a first receiving wall partially enclosing the first filter medium body and extending outwardly away from the first support rim. The second receiving pocket has a second receiving wall partially enclosing the second filter medium body and extending outwardly away from the second support rim.

Claims

1. A filter element comprising:

a filter element housing comprising a first outwardly open receiving pocket and a second outwardly open receiving pocket;

a first filter medium body disposed in the first receiving pocket;

a second filter medium body disposed in the second receiving pocket;

wherein the first and second filter medium bodies delimit a common clean chamber that communicates with at least one outflow opening configured to discharge a purified fluid from the clean chamber;

wherein the first receiving pocket comprises a circumferentially extending first support rim on which the first medium body is supported;

wherein the second receiving pocket comprises a circumferentially extending second support rim on which the second filter medium body is supported;

wherein the first receiving pocket comprises a first receiving wall at least partially enclosing the first filter medium body and extending outwardly away from the first support rim;

wherein the second receiving pocket comprises a second receiving wall at least partially enclosing the second filter medium body and extending outwardly away from the second support rim.

2. The filter element according to claim 1, wherein the first receiving pocket has a circumferentially extending first sealing rim on which the first filter medium body is resting and wherein the second receiving pocket has a circumferentially extending second sealing rim on which the second filter medium body is resting.

3. The filter element according to claim 2, wherein the first and second sealing rims are embodied as an adhesive bead and the first and second filter medium bodies are adhesively connected to the adhesive bead, respectively.

4. The filter element according to claim 2, wherein the first and second sealing rims are embodied as PU foam.

5. The filter element according to claim 2, wherein the first sealing rim is positioned on or adjacent to the first support rim and wherein the second sealing rim is positioned on or adjacent to the second support rim.

6. The filter element according to claim 1, wherein the first and second receiving pockets are arranged diametrically opposed to each other on the filter element housing.

7. The filter element according to claim 1, wherein the first and second receiving pockets are arranged on the same side of the filter element housing.

8. The filter element according to claim 1, wherein the first and second receiving pockets are arranged on different sides of the filter element housing and are arranged angularly relative to each other.

9. The filter element according to claim 1, wherein at least one side of the first and second receiving walls has a reduced height, respectively.

10. The filter element according to claim 9, wherein at least the first receiving pocket has a rectangular cross section.

11. The filter element according to claim 10, wherein the first receiving wall has a rectangular cross section with two long sides and two narrow sides, wherein at least one of the long sides of the first receiving wall has a reduced height relative to a height of the narrow sides.

12. The filter element according to claim 1, wherein at least one of the first and second filter medium bodies has a parallelepipedal shape.

13. The filter element according to claim 1, wherein the first and second filter medium bodies are folded filters.

14. The filter element according to claim 1, wherein the first filter medium body has a size that is different from a size of the second filter medium body.

15. The filter element according to claim 1, wherein the first filter medium body has a geometry that is different from a geometry of the second filter medium body.

16. The filter element according to claim 1, wherein the first filter medium body has a size and a geometry different from a size and geometry of the second filter medium body.

17. The filter element according to claim 1, wherein the filter element housing is a monolithic injection molded plastic part comprising the first and second receiving pockets.

18. A filter device with a filter element according to claim 1 and a filter housing configured to receive the filter element.
