Benefits of technology

The invention describes a filter element that has a support system with a cross-section that tapers as a whole, which helps to increase the effective filter surface area and reduces the amount of material needed. This tapering shape also helps to improve the service life of the filter element. The support system can be made with a foamed adhesive, which reduces the amount of adhesive needed and improves seal tightness, while also allowing for better penetration of uneven surfaces. Overall, this design improves the efficiency and performance of the filter element while reducing production expenses.

Problems solved by technology

The load limit of the filter element is thus increased and thus also its service life.

Embodiment Construction

[0033]In FIG. 1, a filter element 10 according to a first embodiment is shown. The filter element can be mounted in a filter housing, not shown, of a filter for a fluid. With the filter element 10 gaseous or liquid fluids can be filtered. For example, such a filter element 10 can be used in an air filter of an internal combustion engine of a motor vehicle.

[0034]The filter element 10 has an inflow side 12 at the raw fluid side and an outflow side 14 at the clean fluid side. The filter element 10 comprises a filter bellows 17 of filter medium 16 that is zigzag-folded multiple times. A detail of the filter bellows 17 is shown in FIG. 3. Folds 18 of the filter medium 16 extend between the inflow side 12 and the outflow side 14. A fold peak 20 of a fold 18 is positioned at the inflow side 12 and at the outflow side 14, respectively. Lateral surfaces 22 of the filter element 10 that cannot be flowed through are surrounded by a polyester nonwoven which is provided on the side that is facin...

Abstract

A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of international application No. PCT / EP2013 / 051087 having an international filing date of 22 Jan. 2013 and designating the United States, the international application claiming a priority date of 21 Mar. 2012, based on prior filed German patent application No. 10 2012 005 532.3, the entire contents of the aforesaid international application and the aforesaid German patent application being incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention concerns a filter element of a filter for filtering fluids, in particular gases, in particular intake air, in particular of an internal combustion engine, in particular of a motor vehicle, comprising a zigzag-folded filter medium with a raw fluid side and a clean fluid side, wherein at the raw fluid side and / or at the clean fluid side of the filter medium at least one elongate support section is arranged on an appropriate surfac...
