Embodiment Construction

[0031] figure 1 Shows a perspective view of a filter system 100 according to an embodiment of the invention, which can be used, for example, as an air filter for an internal combustion engine, with a tangential inlet 102, a central outlet 104 on the end of the housing and a bottom The dirt outlet 106 of. A circular filter configuration is shown consisting of a housing 108 which is connected to an end cap 110 , for example with a screw or plug connection. When used as an air filter system, the dust-laden air flows into the inlet 102 arranged tangentially to the air filter element mounted inside, so that the air passes in the interior of the housing 108 through the filter element on the The airflow guard moves in a swivel motion. The filter element and the draft guard are not shown in the figures. Due to the swirl effect produced by the rotational movement of the air, centrifugal forces act on the dust particles of the flowing air, so that some of these dust particles can be ...

Abstract

The invention relates to a filter element (10), comprising a filter body (12) having a longitudinal axis (L), a first open or closed end disc (16) arranged at an end face (15), and a second end disc (18) arranged at the opposite end face (17), said second end disc (18) comprising a coupling element (24) which, when installed in a female housing (108), cooperates with a flow guide element (122) mounted on a cover (110) of the housing (108), whereby the filter element (10) is axially guided. The invention further relates to a filter system (100) for removable installation of such a filter element (10).

Description

technical field [0001] The invention relates to a filter element, in particular for use as an air filter for an internal combustion engine, and to a filter system for installing such a filter element. Background technique [0002] An air filter construction is known from DE 20 2009 016 500 U1 in which at least one axial end disk of the filter element is provided with an alignment contour which is radially separated from each end disk . Complementary to this, the filter housing has an alignment counter-contour, which interacts with the alignment contour of the filter element in such a way that the filter element can only move in a predetermined position with respect to its longitudinal center axis. into the filter housing in the rotated position. [0003] In certain applications, a symmetrical flow pattern can be achieved down the filter element in the air filter system. For example, in fresh air installations, an air mass sensor, in particular in the form of a hot-film fl...
