Abstract
A low cost combined air cleaner and resonator includes two housing members which snap together. An air filter is captured between the two members. A first of the members receives the air filter, and the second of the two members has an enlarged plenum to provide a resonator function. The combined air cleaner and resonator thus provides a low cost way of achieving both functions in a system for supplying clean air to a vehicle engine.

A combined air cleaner and resonator assembly comprising:
- a first housing defining a bottom wall, with an inlet opening extending through said first housing to supply an air to be cleaned into said first housing;
- a second housing, said second housing attached to said first housing, said second housing sandwiching an air filter against said bottom wall of said first housing and a wall of said second housing, and said second housing including an enlarged plenum to provide an air resonator function, said second housing including an outlet for supplying air from said enlarged plenum to a vehicle engine.
A combined air cleaner and resonator assembly comprising:
- a first housing defining a bottom wall, with an inlet opening extending through a side wall of said first housing to supply an air to be cleaned into said first housing;
- a second housing attached to said first housing, said second housing having a bottom wall sandwiching an air filter against said bottom wall of said first housing, and said second housing including an enlarged plenum to provide an air resonator function, said second housing including an outlet for supplying air from said enlarged plenum to a vehicle engine;
- and
- air passing through said inlet opening into a space radially outwardly of said filter element, through said filter element, and outwardly of said first housing into said plenum.
