Abstract
The present invention relates to a flat gasket with filter elements. In order to fulfill the increased requirements with respect to cleanliness, there is an increased demand for the integration of filter elements in flat gaskets. The corresponding filter elements mainly serve for picking of impurities accrued during production as well as other residues circulate via the operational fluids, especially during the initial period of operation of an internal combustion engine or a vehicle.
