摘要
The present invention refers to a filter body for filtering a gas stream, especially for purifying exhaust gases issued by an internal combustion engine, comprising an inlet (1) for receiving a gas stream to be purified, an outlet (4) for discharging the purified gas stream, a chamber (2) having a casing (7) determining an inner surface and at least one filter member (3) of inherent porosity arranged within the chamber (2), the inlet (1) and outlet (6) being determined by closing plates (6), wherein according to the present invention the filter member (3) is made of an active material comprising inner channel shaped openings for receiving the gas stream and within the chamber (2) directing plates (10) are arranged, further in the chamber (2) each directing plate (10) is partly connected and partly disconnected with the inner surface of the casing (7), and each disconnection determines spacings (5), wherein the sum of the cross-sectional areas of the spacings (5) is equal with or greater than the cross-sectional area of the outlet (4).
