Abstract: For a method for producing a filter element provided with a sealing part, wherein the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, a compensation space connected to the casting chamber is provided for the expansion of the sealing material.

Abstract: An air filter has a filter housing and a filter element inserted in the interior of the filter housing. The filter element has an inflow surface and an outflow surface and a filter medium that extends between inflow and outflow surfaces. The filter element has a circumferentially extending seal arranged in the area of the inflow surface or outflow surface and interacting in the mounting position with the sealing surface of the filter housing to separate inlet and outlet of the air filter. A support device clamps the filter element transversely to the insertion direction in the filter housing by a transverse clamping action in a support area that is spaced from the seal. The transverse clamping action results by an insertion movement of the filter element into the filter housing by interaction of the filter element with inner sides of the filter housing.

Abstract: A flat filter element has a filter medium and a sealing section that seals the flat filter element relative to a filter housing. A support element section is arranged on a circumferential side of the filter medium outside of the sealing section and supports the flat filter element relative to an inner side of the filter housing, wherein the support element section projects past the filter element in at least one direction. The filter housing has a mounting opening through which the flat filter element is inserted into the interior where the flat filter element is arranged such that the inlet is separated from the outlet of the filter housing. A projection arranged on an inner side of the filter housing supports under mechanical tension the support element section of the flat filter element in a mounting position of the flat filter element in the interior.

Abstract: A flat filter element to be mounted in a filter housing has an inflow surface and an outflow surface downstream of the inflow surface in a flow-through direction. A filter medium extend between the inflow surface and the outflow surface. A sealing section extends circumferentially relative to the flow-through direction. A seal fastened to or interacting with the sealing section is provided, wherein the seal, when the flat filter element is mounted in a filter housing, separates an inlet of the filter housing for air to be purified from an outlet of the filter housing for purified air. A first functional element section is arranged on at least one circumferential side of the filter medium so as to be spaced apart from the circumferentially extending sealing section. The first functional element section is attached to a lateral strip and the lateral strip is attached to the filter medium.

Abstract: A filter device has a filter element arranged in a filter housing. The filter device has additionally an adsorber element that adsorbs hydrocarbons. The adsorber element is arranged in a separate adsorber housing connected to the filter housing.

Abstract: A filter device for filtration of gaseous fluids has a multi-part housing with a first housing part and a second housing part connected to one another in a mounted state of the multi-part housing. A filter element is insertable into the multi-part housing. A connecting device penetrates the filter element and provides a connection between the first and second housing parts. The connecting device has at least one first housing projection monolithically formed on the first housing part. The connecting device further has a damping element arranged between the at least one first housing projection and the second housing part.

Abstract: An air filter system of a motor vehicle has an air filter housing with a housing part of a moisture-sensitive plastic material and an air passage section with a circumferentially extending passage wall, wherein the passage wall of the air passage section is integrally formed of identical material on the housing part of the air filter housing. A mass air flow sensor is arranged in the air passage section. A plastic insert of a moisture-insensitive plastic material is disposed on an inner side of the passage wall of the air passage section and lines the passage wall.

Abstract: An air filter insert including at least one filter element (2; 4; 11) and a seal (3; 7) extending along outer edges of one side of the filter insert (2; 4; 11) and via which the filter insert is sealingly seated against housing sections (5, 6) of a surrounding filter housing. The filter insert (2; 4; 11) is configured such that the air can easily flow into or out of the structural space on the one side of the filter element with a minimum pressure drop. The filter insert (11) may be at least partially covered on the inflow and/or discharge side by a semi-permeable component (12), which at least partially equalizes the pressure distribution in the air stream.

Abstract: An insert filter 10 for cleaning a gas stream, particularly for the intake air of an internal combustion engine or an air-conditioning unit, which includes a filter frame 11, a filter element 12 placed in the filter frame 11, and a shaft cover 13 and which is placed in the shaft 14 of a duct system 15 that guides the gas stream such that an unfiltered side 16 is separated from a clean side 17 by the filter element 12 and the filter frame 11. The shaft cover 13 closes a shaft opening 24 through which the insert filter 10 is inserted in the shaft 14. The filter frame 11 is connected to the shaft cover 13 so that the filter frame 11 can be removed from the shaft 14 without any need for additional removal aids by simply pulling on the shaft cover 13.
