Abstract

A filter element has a filter medium body with a plurality of filter segments that are joined to one another, of which at least two filter segments run adjacent and delimit an interposing intermediate space in which a support element is arranged for support on a housing component.

First claim

1 . A filter element, especially for gas filtration, comprising:
a filter medium body ( 2 ) having a plurality of filter segments; wherein at least two filter segments ( 2 c , 2 d ) run adjacent to one another and delimit an interposing intermediate space ( 11 ); wherein a support element ( 7 ) for support on a housing component ( 17 ) is arranged within the intermediate space ( 11 ).

2 . The filter element in accordance with claim 1 , wherein
the filter element includes a support grid that is arranged on a lateral surface of the filter medium body ( 2 ); wherein the support element ( 7 ) is connected to the support grid ( 6 ).

3 . The filter element in accordance with claim 1 , wherein
the two filter segments ( 2 c , 2 d ) run approximately parallel to one another.

4 . The filter element in accordance with claim 1 , wherein
the two filter segments ( 2 c , 2 d ) are joined via a connecting segment of the filter medium body ( 2 ).

5 . The filter element in accordance claim 1 , wherein
the at least two filter segments delimit the intermediate space ( 11 ) as a U-shaped intermediate space.

6 . The filter element in accordance with claim 1 , wherein
the support element ( 7 ) is arranged on the outflow or clean side of the filter segments.

7 . The filter element in accordance with claim 1 , wherein
the filter medium body ( 2 ) has a W-shape; wherein the two filter segments ( 2 c , 2 d ) delimiting the intermediate space ( 11 ) are arranged between outer filter segments ( 2 a , 2 b ) of the filter medium body ( 2 ).

8 . The filter element in accordance with claim 1 , wherein
the support element is embodied as a support clamp ( 7 ) that has a receiving segment ( 12 ) for the housing component ( 17 ); wherein the receiving segment ( 12 ) is delimited by a narrow part ( 13 ).

9 . The filter element in accordance with claim 1 , wherein
the filter medium body ( 2 ) has an admission or discharge port ( 10 ), laterally delimited by filter segments ( 2 a , 2 b ), for the fluid to be cleaned; wherein the admission or discharge port ( 10 ) is edged with a circumferential sealing element ( 15 ).

10 . The filter element in accordance with claim 1 , wherein
an end plate ( 4 , 5 ) is arranged at each of the two opposing end faces of the filter medium body ( 2 ).

11 . The filter element in accordance with claim 1 , wherein
the filter medium body ( 2 ) is embodied as a pleated filter bellows.

12 . A filter device comprising:
a filter element ( 1 ) in accordance with claim 1 ; a filter housing ( 17 ) into which the filter element is received.

13 . A filter device in accordance with claim 12 , wherein
a support strut ( 14 ) is integrally formed with the filter housing ( 17 ), on which support strut ( 14 ) the support element ( 7 ) arranged on the filter medium body ( 2 ) is supported when the filter element ( 1 ) is placed into the filter housing ( 17 ).
