Embodiment Construction

[0040] figure 1 A filter system 100 according to an exemplary embodiment of the invention is shown in a perspective view, which can be used, for example, as an air filter for an internal combustion engine. The filter system 100 has a tangential inlet 102, a central outlet 104 at the end face of the housing, and a dirt outlet 106 at the bottom side of the housing. A circular filter arrangement is shown comprising a housing 108 closed by a cover 110, such as a screw closure or a bayonet coupling closure. When used as an air filter system, dust-laden air flows in through the inlet 102 arranged tangentially to the air filter element arranged in the interior so that due to the inflow protection provided at the filter element The device causes the air in the interior of the housing 108 to swirl. Filter elements and inflow protectors are not shown in the figures. Due to the cyclone effect caused by the rotational movement of the air, centrifugal forces act on the dirt particles en...

Abstract

The invention relates to a filter element and a filter system having the filter element. The filter element has a filter body with a longitudinal axis, wherein the filter body has a first end and a second end opposite to the first end in a direction of the longitudinal axis, the first end havs a first end surface, and the second end has a second end surface. The filter body is provided with an inner circumferential surface and an outer circumferential surface that are permeable to a medium to be filtered. A first end disk is disposed at the first end surface, and a second end disk is disposedat the second end surface. The outer circumferential surface of the filter body has at least one fluid-tight area that is impermeable to the medium to be filtered. The fluid-tight area is an inflow protector or an incorrectly handled protector resting on the outer circumferential surface.

Description

technical field [0001] The invention relates to a filter element, in particular for use as an air filter in an internal combustion engine, and to a filter system for installing such a filter element. Background technique [0002] DE 297 80 439 U1 discloses an air filter arrangement in which the filter element and housing are constructed such that a "pre-cleaning" process is carried out which removes coarse dirt from the air before it comes into contact with the filter element. For example, the housing is configured with respect to the incoming air flow such that the air is first directed around the filter element (or so as to circumscribe it) in a circular flow or helical pattern, so that the coarse dirt particles or suspended particles are already dislodged due to the cyclone effect. Separated from air. [0003] In conventional systems, incoming air causes considerable turbulence at the inlet opening into the system. This turbulence may stress or weaken the folds of the p...
