ABSTRACT:
A tubular filter with porous silicon carbide for filtering particles of soot out of the exhaust gas of a diesel engine is mounted between two holders in a gas duct where one of the holders is spring loaded and the other has a bore that communicates with a bore connecting with the inside of the filter. The holders have surfaces facing the filter that are concavely spherical. The filter ends are provided with matching convexly spherical surfaces and they are directly on the filter ends or on an intermediate piece tightly seated on the filter end. The spherical surfaces are not necessary at the spring loaded holder and for some embodiments the holder can have a convexly spherical surface. The placing of the filter in a duct does not always permit the holders to be exactly opposite each other, but the filter mounting can be accommodated to somewhat offset holders because the gas tightness of the compression joints remain tight when the position of the filter is slightly oblique in the duct. The same tightness is preserved if for some reason the ends of the tubular filter are in planes that are not quite parallel to each other.
