Problems solved by technology

However, it has been found that during operation, especially during operation of the vehicle, shocks or vibrations occur which cause relative movement between the filter element and the filter housing, thereby making the connection between the filter element and the filter housing under heavy load
This can lead to increased wear of the filter element in the area of ​​the end disc
In particular, the sealing effect between the end disc and the nozzle may be weakened

Embodiment Construction

[0023] according to figure 1 , the filter device 1 includes a filter housing 2 and a filter element 3 disposed therein. The filter device 1 is preferably configured as an air filter of a fresh air system via which fresh air can be supplied to the motor vehicle or the interior of the vehicle, or preferably to the internal combustion engine. In this case the filter element 3 comprises an air filter element.

[0024] The filter housing 2 has an inlet 4 , a primary outlet 5 and a secondary outlet 6 . Furthermore, the filter housing 2 surrounds a receiving chamber 7 in which the filter element 3 is arranged. In the filter housing 2 or receiving chamber 7 , the filter element 3 separates a raw material chamber 8 , which communicates with the inlet 4 , and a purification chamber 9 , which communicates with the two outlets 5 , 6 . In this example, the gas flow flows from the outside inwards through the filter element 3 such that the filter element 3 surrounds the purification chamb...

Abstract

The present invention relates to a filter element, in particular for an air filter of a fresh air system of a vehicle or an internal combustion engine. The filter element comprises: an annular filter body made of a filter material, an internal support frame, wherein said filter body is supported radially on the inside of said internal support frame, at least one end disk disposed at the filter body and the internal support frame, wherein the end disk has a central disk opening, a radial seal arranged coaxially to the disk opening, the internal support frame has a plurality of radial centering elements distributed in the circumferential direction and projected inwardly and extending to a radial end on the inside at an inner wall of the end disk, wherein the inner wall encloses the disk opening.

Description

technical field [0001] The invention relates to a filter element, in particular an air filter for an internal combustion engine or a fresh air system of a vehicle. Furthermore, the invention relates to a filter device, in particular an air filter for a fresh air system of a motor vehicle or an internal combustion engine, in which at least one such filter element is installed. Background technique [0002] From DE 10159097 a filter device is known which has a filter element in a filter housing. The filter element has an annular filter body made of filter material and an inner support frame at which the filter body is internally supported radially. Furthermore, the filter element has two end disks arranged on axially opposite sides on the filter body and on the inner support frame. Both end discs have a central disc opening. The nozzle of the main outlet can be inserted into the disc opening of one end disc. In the disc opening of the other end disc, a flange is fixedly in...
