ABSTRACT:
In a blower housing arrangement for a motorized vehicle of the type with a blower encased by a housing followed by a duct system, a preferably open-pore foam material is utilized for noise damping, this foam material being sealed at least on the inside of the housing by means of a skin. This foam material is locally supported and bordered along the edges by wall sections of the housing and/or of the duct system so that, in this zone, the foam material is the sole means of forming the wall. The wall sections constitute a skeleton which, at least during normal driving operation, is dimensionally rigid and supportive and which serves for the accommodation of installation components, operating parts, and mounting elements.
