  • Noise attenuating drying apparatus for motor vehicles
    Patent number: 7028416
    Abstract: An air duct for a motor vehicle air dryer has an outer shell defining an inner surface. A porous, fluid permeable lining for attenuating noise caused by turbulent air flow through the air duct is positioned on the shell inner surface, and defines an inner surface. The lining is retained in place by a relatively rigid expanded mesh adjacent the inner surface of the lining. The interior lining and mesh is preferably removable from the outer shell, but may be permanently mounted therein.
