  • Patent number: 4227898
    Abstract: An air cleaner to remove particulate matter from an air stream, and to dampen sounds emitted to the air cleaner by an internal combustion engine receiving air from the air cleaner. Such sounds are commonly conducted upstream through conventional air cleaners and are heard emitting from the inlet of the air cleaner. The air cleaner of this invention both effectively cleans the air and diminishes said sounds. The air cleaner has a partition dividing its interior into a unit chamber holding a filter element unit, and a passage chamber receiving air to be cleaned and conveying it to an opening in the partition leading to the unit chamber. The shape and location of the passage chamber assist in the reduction of sound transmitted upstream.
