Abstract

A filter housing has a first aperture, a tube connected to and extending from the first aperture, at least one second aperture, and at least one filter connected to the at least one second aperture for filtering air entering the at least one second aperture. A portion of air entering the filter housing flows out of the filter housing via the first aperture and through the tube. Another portion of air entering the filter housing flows out of the filter housing via the at least one second aperture around the tube separately from the portion of air flowing out of the filter housing via the first aperture.

First claim

What is claimed is:

1. A filter housing comprising:
a central raised portion;
a floor extending from a bottom of the central raised portion; and
a vertical wall extending from the floor along three sides of the central raised portion, the floor being disposed between the central raised portion and the vertical wall;
a first aperture defined in the raised portion;
a tube connected to and extending inside the raised portion from the first aperture;
at least one second aperture defined in the raised portion; and
at least one filter connected to the at least one second aperture for filtering air entering the at least one second aperture;
a portion of air entering the filter housing flowing out of the filter housing via the first aperture and through the tube, and
another portion of air entering the filter housing flowing out of the filter housing via the at least one second aperture around the tube and over an exterior surface of the tube separately from the portion of air flowing out of the filter housing via the first aperture.

2. The filter housing of claim 1 , further comprising a seal connected to a bottom of the floor.

3. The filter housing of claim 1 , further comprising drain apertures defined in a bottom of the vertical wall.

4. A filter housing comprising:
a central raised portion;
a first aperture defined in the raised portion;
a tube connected to and extending inside the raised portion from the first aperture;
at least one second aperture defined in the raised portion; and
at least one filter connected to the at least one second aperture for filtering air entering the at least one second aperture;
a portion of air entering the filter housing flowing out of the filter housing via the first aperture and through the tube, and
another portion of air entering the filter housing flowing out of the filter housing via the at least one second aperture around the tube and over an exterior surface of the tube separately from the portion of air flowing out of the filter housing via the first aperture,
the at least one second aperture including:
two second apertures defined in a top of the central raised portion; and
six air intake assembly apertures defined in sides, front and back of the central raised portion.

5. A filter housing comprising:
a first aperture;
a tube connected to and extending from the first aperture;
at least one second aperture; and
at least one filter connected to the at least one second aperture for filtering air entering the at least one second aperture,
a portion of air entering the filter housing flowing out of the filter housing via the first aperture and through the tube, the portion of air not flowing through the at least one filter; and
another portion of air entering the filter housing flowing out of the filter housing via the at least one second aperture around the tube and over an exterior surface of the tube separately from the portion of air flowing out of the filter housing via the first aperture, the other portion of air flowing through the at least one filter.

6. The filter housing of claim 5 , further comprising a central raised portion;
wherein the first aperture and the at least one second aperture are defined in the raised portion; and
wherein the tube extends inside the raised portion.

7. The filter housing of claim 6 , further comprising:
a floor extending from a bottom of the central raised portion; and
a vertical wall extending from the floor along three sides of the central raised portion, the floor being disposed between the central raised portion and the vertical wall.

8. The filter housing of claim 7 , further comprising a seal connected to a bottom of the floor.

9. The filter housing of claim 7 , further comprising drain apertures defined in a bottom of the vertical wall.

10. The filter housing of claim 6 , wherein the at least one second aperture includes:
two second apertures defined in a top of the central raised portion; and
six air intake assembly apertures defined in sides, front and back of the central raised portion.

11. The filter housing of claim 5 , further comprising a latch.

12. The filter housing of claim 5 , further comprising a grating provided over the first aperture.

13. The filter housing of claim 5 , wherein the at least one filter is a screen filter.

14. The filter housing of claim 5 , wherein the at least one second aperture surrounds the first aperture.

15. The filter housing of claim 5 , wherein the at least one filter is removable.

16. The filter housing of claim 5 , wherein:
the at least one filter is at least one second filter; and
the filter housing further comprises at least one first filter connected to the first aperture for filtering air entering the first aperture.

17. The filter housing of claim 16 , wherein the at least one first filter is removable.

18. A vehicle comprising the filter housing of claim 5 .

19. The vehicle of claim 18 , further comprising:
an internal combustion engine;
a continuously variable transmission (CVT) operatively connected to the internal combustion engine;
wherein:
the first aperture supplies air to one of:
at least one air intake port of the engine; and
an interior of a housing of the CVT; and

the at least one second aperture supplies air to another one of:
at least one air intake port of the engine; and
an interior of a housing of the CVT.

20. The vehicle of claim 19 , wherein:
the first aperture supplies air to the at least one air intake port of the engine; and
the at least one second aperture supplies air to the interior of the housing of the CVT.
