Abstract

An air cleaner for purifying air is disclosed. The air cleaner includes a housing having a first shell mounted to a second shell. The air cleaner also includes a filter disposed within the second shell and having a first side and a second side. Also, the air includes a flexible seal disposed between the first side of the filter and the first shell of the housing. At least one cam is rotatably mounted to the second shell and adapted to selectively engage the second side of the filter to compress the seal between the first side of the filter and the first shell of the housing.

Claims

1. An automotive air cleaner for purifying combustion air for an internal combustion engine, comprising:

a housing having a first shell coupled to a second shell, an air inlet disposed to receive combustion air, and an air outlet disposed to transmit combustion air;

an air filter element disposed within the second shell and having a first side and a second side;

a flexible seal disposed between the first side of the filter and the first shell of the housing; and

at least one cam rotatably mounted to the second shell and adapted to selectively engage the second side of the filter to compress the seal between the first side of the filter and the first shell of the housing.

2. The air cleaner of claim 1 further comprising a container supporting the second side of the filter.

3. The air cleaner of claim 2 wherein the second shell further includes a cavity and the container is disposed within the cavity.

4. The air cleaner of claim 3 wherein the housing is configured to receive the container for slidable placement between the first shell and the second shell.

5. The air cleaner of claim 4 wherein when the cam is rotated the filter element is moved toward the first shell to compress the seal against the first shell.

6. The air cleaner of claim 5 wherein the first shell further includes a sealing surface and the seal is disposed against the sealing surface.

7. The air cleaner of claim 6 wherein the filter is generally rectangular shaped.

8. The air cleaner of claim 7 wherein the housing is plastic.

9. The air cleaner of claim 7 wherein the cam further includes a stem.

10. The air cleaner of claim 4 wherein the cam further includes a first width greater than a second width.

11. The air cleaner of claim 4 wherein the seal is mounted to the first side of the filter.

12. The air cleaner of claim 4 wherein the housing further includes a first air conduit integral with the first shell and a second air conduit integral with the second shell.

13. An air filter for filtering combustion air for an internal combustion engine disposed in a housing, the housing having a first shell mounted to a second shell, an inlet mounted to the first shell, an outlet mounted to the second shell, and at least one cam rotatably mounted to the second shell, the air filter comprising:

a container adapted to be selectively engaged by the cam;

a filter element adapted to filter the combustion air and having a first side and a second side, the second side of the filter element supported by the container; and

a flexible seal disposed between the first side of the filter element and the first shell;

wherein the seal forms a closure between the first side of the filter element and the first shell to increase the amount of air directed through the filter element.

14. The air filter of claim 13 wherein the container is configured for slidable placement in the housing and between the first shell and the second shell.

15. The air filter of claim 14 wherein the second side of the filter element is engageable with the cam to move the filter element toward the top shell and thereby compress the seal between the filter element and the top shell when the cam is rotated.

16. The air cleaner of claim 15 wherein the seal is mounted to the periphery of the first side of the filter element.

17. A method of installing an air filter in an air cleaner having a housing, the housing having a first shell with a first air conduit and mounted to a second shell with a second air conduit, an air filter having a first side and a second side, a flexible seal disposed between the first side of the air filter and the first shell of the housing, and at least one cam rotatably mounted in the housing, the method comprising:

sliding the filter into the second shell;

rotating the cam to engage the second side of the filter;

moving the filter toward the first shell; and

compressing the seal between the first side of the filter and the first shell.

18. The method of 17 wherein the step of sliding the filter into the second shell further comprises the step of sliding the filter into a cavity of the second shell.

19. The method of claim 18 wherein the step of rotating the cam further comprises the step of rotating a stem of the cam that is disposed outside the housing.

20. The method of claim 19 wherein the filter is substantially planar and wherein the step of sliding the filter further includes the step of sliding the filter into the cavity in a direction parallel to a plane of the filter.
