Embodiment Construction

[0046] In the drawings, the same or similar components are marked with the same reference numerals. The drawings show examples only and are not to be construed as limiting.

[0047] figure 1 A longitudinal section through a filter system 100 according to one exemplary embodiment of the invention is shown with a primary filter element 50 which surrounds a secondary element 10 on its clean side.

[0048] The filter system 100 comprises a housing 110 consisting of a tank 112 and a cover 114 which can be removed. figure 2 Details of the bottom area of ​​the housing 110 are shown.

[0049] Housing 110 can be configured, for example, cylindrically. An inlet sleeve, not visible in the drawing, is arranged on housing 110 for supplying the fluid to be filtered, in particular air. The inlet sleeve can be arranged radially or tangentially on the housing 110 . The axial position is close to the bottom 120 of the housing 110 in a region in which an inflow protection 124 is arranged i...

Abstract

The invention relates to a secondary element (10) which has a longitudinal axis (L) and two opposite ends (12, 14), comprising a filter medium (16) arranged around the longitudinal axis (L), wherein one of the ends (14) is open and the opposite end (12) is connected to a closed end disk (20) in a sealed manner, and the end disk (20) has a connecting means (22) which when mounted as intended is provided to interact with a connecting means (156) of a support tube (150) of a filter system (100) in order to fix the secondary element (10) on the support tube (150). The invention further relates to a filter system (100) comprising such a replaceable filter secondary element (10).

Description

technical field [0001] The invention relates to a secondary element for a filter system, in particular for an air filter system of an internal combustion engine, and to a filter system having such a secondary element. Background technique [0002] It is known to use air filters in order to filter the combustion air for internal combustion engines in motor vehicles, such as passenger cars, commercial vehicles, work machines, agricultural vehicles, but also stationary generators or the like. Such air filters generally comprise a housing, an air inlet and an air outlet, wherein a removable and replaceable main filter element is arranged in the housing. The housing usually comprises a service cover or an access cover for accessing the filter element received inside in case of maintenance. For this purpose, the filter element can be disassembled and replaced by a factory-fresh filter element, reconditioned and used again, or replaced by a previously used but reconditioned filter...
