Problems solved by technology

[0004] A conically shaped filter element is known from document EP 1558360 B1, however, due to the conical shape (which opens at an angle opposite the discharge direction of the filter system) it requires a greater installation space
Folded secondary elements are also known, but require additional installation space compared to secondary elements with a flat filter medium

Embodiment Construction

[0044] In the drawings, identical or similar components are numbered with the same reference numerals. The drawings show examples only and are not to be construed as limiting.

[0045] figure 1 Shows a perspective view of a secondary filter system 100 with a cyclone separator 36 according to an embodiment of the invention, with a tangential inlet 102, a central outlet at the housing end side Dirt exits portion 104 and bottom side from portion 106 . A circular filter structure is shown, which contains a housing 108 which has a housing wall 112 and is closed with a cover 110 (for example with a screw connection or a bayonet connection). When used as an air filter system, dust-laden air flows into the inlet 102 which is arranged tangentially with respect to the air filter element installed inside, so that the air is passed in the interior of the housing 108 by the inflow at the filter element The guard is placed in a swivel motion. The filter element and the inflow protection...

Abstract

The present invention relates to a filter system with filter elements, in particular to a filter system (100) with one or more filter elements equipped with at least one filter medium (56), wherein at least one filter element is Axis extension. The filter system here comprises a housing (108) with a housing wall (112) and a cover (110), an inlet arranged on the housing for feeding the fluid to be filtered, in particular air, and a The exit part for leading out the filtered fluid. In this case, the filter medium is folded in a zigzag pattern and has a plurality of outer edges extending along the longitudinal axis of the folds ( 62 ) and inner edges lying opposite the outer edges on the side opposite to the filter medium. Edge. Furthermore, the filter medium has a flow resistance that can vary along the longitudinal axis. Furthermore, the invention relates to a filter element with such a filter medium for exchangeable installation in such a filter system.

Description

technical field [0001] The invention relates to a filter system with a filter element, especially for use as an air filter for an internal combustion engine, and to a filter element for installation in such a filter system. Background technique [0002] The construction of filter systems in which circular filter elements are used is known from the prior art. In use, the round filter element often flows from the outside to the inside, the filtered fluid being guided from the cylindrical interior through openings in the cover or base of the round filter element to the outlet of the filter housing. The diameter of the outlet opening in the cover of the circular filter element is limited by the diameter of the interior of the filter element. The diameter of the outlet opening is obtained from the diameter of the filter element minus the fold height of the filter medium used. [0003] On the one hand, with the same external dimensions, the greatest possible fold height allows a...
