Abstract

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.
