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.
Claims10
An air cleaner for an air induction system of an automotive engine having a throttle body controlling air flow into said engine, said air cleaner comprising:
- a housing having an interior space defined therein, including an air cleaner fllter element cavity and also having an air intake port communicating with said filter element cavity in said interior space;
- a hollow air cleaner filter element defining a closed space having an opening therein;
- a hose coupling fitting engageable with said opening of said air cleaner filter element to be sealed thereto;
- said air cleaner filter element with said hose coupling fitting mounted thereto insertable through an outlet opening in said housing to be received in said air cleaner filter element cavity in said housing interior space, said air cleaner filter element not sealed to said housing;
- a hose sealed at one end to said hose coupling fitting and at the other end said throttle body;
- and
- said hose coupling fitting detachably connected to said housing to secure said air filter element positioned in said air cleaner filter element cavity.
