  • Patent number: 5865863
    Abstract: A combined air cleaner and noise attenuating resonator device including a hollow cylindrical air cleaner element pressed to a fitting on a hose, the fitting latched to the housing in a position holding the air cleaner filter element within a cavity in a housing. An expansion chamber and a Helmholtz resonator chamber are both defined in part in the housing and by an insert piece within the housing which also forms an air flow passage in fluid communication with each chamber.
