Abstract
A particulate filter includes a housing having opposite ends, a pair of support walls adjacent respective opposite ends of the housing and defining therein an interior, and a pair of pure gas chambers defined at respective opposite ends of the housing at sides of the respective support walls outwardly of the interior. A plurality of elongated filter bodies are supported by the support walls to extend therebetween within the housing with longitudinal axes of the filter bodies extending parallel. The filter bodies define outwardly thereof within the housing a raw gas chamber in the form of a plurality of elongated raw gas compartments. Hollow interiors of the filter bodies define respective elongated pure gas channels. Each pure gas channel opens into at least one of the pure gas chambers. A raw gas supply inlet connection opens into the interior of the housing at a position between the pair of support walls such that raw gas is supplied to the exterior of the filter bodies in a direction transverse to the direction of elongation of the raw gas compartments and transverse to the longitudinal axes of the filter bodies.
