Abstract

A filter for the separation of impurities or contaminants from a fluid or gaseous medium, especially of harmful components from the exhaust fumes of an internal combustion engine, with a filter body having a plurality of inlet and outlet channels, whereby the inlet channels are separated from the outlet channels by filter walls forming reaction spaces. The filter bodies consist of a plurality of compression molded, high-temperature-resistant filter plates which, arranged one above the other, form a plurality of flow channels between themselves. For the formation of inlet and outlet openings, the channels are each open on one filter body end face and closed on the opposite end face. The channel closure and the connection of adjacent filter plates takes place alternately on each end face by two adjacent filter plates being pushed into and tightly surrounded by stirrup parts which extend over and grip the entire width of the filter plate adjacent end edges.
