Embodiment Construction

[0016] The filter device 1 according to the invention, which is designed in particular for filtering intake air in an internal combustion engine not described in detail, has a filter housing 2 in which a filter insert 3 , in particular of the ring type, is arranged exchangeably. filter element. In this case, the filter insert 3 separates the raw side 5 from the clean side 4 in a known manner and is substantially cylindrical, ie flows radially from the outside to the inside. On the end side, the filter insert 3 is delimited by two end disks 6 and 7 , wherein in this case an axial seal 8 is arranged on the end disk 7 , which is combined with the sealing of the filter housing 2 . The face 9 results in a seal between the raw side 5 and the clean side 4 . Likewise, a support 10 fixed to the filter housing and arranged on the filter housing side is provided, on which the filter insert 3 is supported in such a way that the filter insert with its axial seal rests securely against the...

Abstract

The invention relates to a filter device. The filter device is especially used for filtering intake air of internal combustion engines. The filter device is provided with a filter housing (2), the filter housing is provided with a filter element (3) which is arranged in the filter housing in a replaceable mode, the filter element separates an original side from a purification side and is basicallydesigned to be cylindrical, an axial seal (8) is arranged on an end disk (7) of the filter element, a sealing surface (9) of the filter housing is combined to cause sealing between the original sideand the purification side, the filter device further comprises a support (10) which is fixed to the filter housing. The filter element is supported on the bracket in the following manner; namely, thefilter element is reliably attached to the sealing surface of the filter shell through the axial sealing piece of the filter element. Wherein an elastic device (11) is arranged on at least one end disc (6, 7) of the filter element, which elastic device is elastically supported on the support when the filter element is inserted into the filter housing, and the filter element is pre-tensioned with respect to the sealing surface of the filter housing by means of the axial seal thereof.

Description

technical field [0001] The invention relates to a filter device according to the preamble of claim 1 , in particular for filtering intake air of an internal combustion engine. Furthermore, the invention relates to a filter insert which is suitable for a filter arrangement of this type. Background technique [0002] Filter devices of this type are sufficiently known, in which the filter insert is fastened in the filter device, for example by means of clamping screws, or fixed or pretensioned in the filter device by means of a cover of the filter housing. Due to the extremely limited space conditions in modern engine compartments or vehicles in general, it is presumably necessary that the generally cylindrical filter element be mounted or removed transversely with respect to its cylinder axis, so that in this case the cover Appears as part of the side of the filter housing. Here, with this type of housing construction, there is the problem that the axial offset of the filter...
