The invention concerns a filter insert () that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing () that can be separated along a separating plane () and the exchangeable filter insert () extending in an axial direction (). Two housing parts () of the filter housing () are sealed relative to one another along the separating plane () by means of a seal (). The seal () is secured slidably and captively in the axial direction () on the filter insert ().

Exchangeable filter insert

A filter closure system has a connecting head with a connecting web and further has a connecting end at an end face of a filter housing. The connecting head and the connecting end are matched to one another. The connecting end is pushed onto the connecting head in a mounting direction into a mounted state on the connecting head so as provide a seal-tight connection in the mounted state. The connecting end and the connecting web that extends in the mounting direction are provided with a micro toothing. When pushing the connecting end onto the connecting head in the mounting direction, the micro toothing connects by positive locking action the connecting end and connecting head with one another. The engagement of the micro toothing between connecting end and connecting head is realized along a flank of connecting web and connecting end which flank extends in the mounting direction.

Filter closure system

A filtering device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A cover disk closes off the filter housing. The cover disk consists of two individual disks and a central flow connection connects the two individual disks. The two individual disks and the flow connection form a common plastic component.

Filtering system, in particular for filtering liquids in internal combustion engines

A filter, in particular for the lubricating oil of an internal combustion engine, which includes a pot-shaped filter housing ( ), a support tube ( ) disposed therein and a filter element ( ) secured on the support tube ( ). The filter element is essentially made up of a filtering material which is folded in a pleated manner and has plates ( and ) at its ends. The filter housing provides a direct seal between itself and a flange ( ), and the support tube is provided with a screw-on thread ( ).
