## Abstract

A vehicle includes an air cleaner box assembly disposed within an engine compartment. The air cleaner box assembly includes a moveable shell portion and a stationary shell portion. The moveable shell portion includes an upper surface disposed adjacent a hood, and defines a filtered air chamber. The stationary shell portion is attached to a structure, and defines an unfiltered air chamber. A filter element is attached to and supported by the moveable shell portion. The filter element separates the filtered air chamber and the un-filtered air chamber. Each of a plurality of spring loaded guide members slideably connect the moveable shell portion and the stationary shell portion, and guide the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position.

## Claims

### Claim 1

An air cleaner box assembly comprising:
a moveable shell portion defining a first air chamber;
a stationary shell portion defining a second air chamber;
a filter element attached to and supported by one of the moveable shell portion or the stationary shell portion, and separating the first air chamber and the second air chamber; and
a guide member slideably connecting the moveable shell portion and the stationary shell portion for guiding the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position;
wherein the moveable shell portion is moveable relative to the stationary shell portion a maximum distance along the path, and wherein the stationary shell portion provides a free space along the path that does not interfere with the movement of the moveable shell portion.

### Claim 2 (depends on 1)

The air cleaner box assembly set forth in claim 1, wherein the guide member includes a spring biasing the moveable shell portion into the expanded position, and wherein the spring yields in response to a force applied to the moveable shell portion to allow movement of the moveable shell portion along the path toward the stationary shell portion and into the compressed position.

### Claim 3 (depends on 2)

The air cleaner box assembly set forth in claim 2, wherein the guide member includes a pin fixedly attached to the stationary shell portion, and wherein the pin includes a central axis extending substantially parallel with the path of the moveable shell portion.

### Claim 4 (depends on 3)

The air cleaner box assembly set forth in claim 3, wherein the spring is a coil spring coiled around the pin.

### Claim 5 (depends on 4)

The air cleaner box assembly set forth in claim 4, wherein the spring is disposed between the moveable shell portion and the stationary shell portion.

### Claim 6 (depends on 5)

The air cleaner box assembly set forth in claim 5, wherein the guide member includes a nut attached to the pin and securing the moveable shell portion relative to the pin.

### Claim 7 (depends on 1)

The air cleaner box assembly set forth in claim 1, wherein the moveable shell portion includes a first shell portion and a second shell portion removeably attached to the first shell portion.

### Claim 8 (depends on 7)

The air cleaner box assembly set forth in claim 7, wherein the filter element is secured in place relative to both the first shell portion and the second shell portion.

### Claim 9 (depends on 7)

The air cleaner box assembly set forth in claim 7, further comprising a plurality of fasteners interconnecting the first shell portion and the second shell portion.

### Claim 10 (depends on 7)

The air cleaner box assembly set forth in claim 7, wherein the filter element includes a filter seal disposed between the first shell portion and the second shell portion for sealing the first air chamber around a periphery of the filter element.

### Claim 11 (depends on 1)

The air cleaner box assembly set forth in claim 1, wherein the first air chamber is a filtered air chamber, and the second air chamber is an un-filtered air chamber.

### Claim 12 (depends on 1)

The air cleaner box assembly set forth in claim 1, wherein the stationary shell portion includes a stationary wall extending along the path and defining an opening.

### Claim 13 (depends on 12)

The air cleaner box assembly set forth in claim 12, wherein the moveable shell portion includes a central wall at least partially positioned within the opening of the stationary wall, such that the central wall slides within the opening of the stationary wall.

### Claim 14 (depends on 13)

The air cleaner box assembly set forth in claim 13, further comprising a second chamber seal disposed between the moveable shell portion and the stationary shell portion for sealing the second air chamber between the moveable shell portion and the stationary shell portion.

### Claim 15 (depends on 14)

The air cleaner box assembly set forth in claim 14, wherein the second chamber seal is disposed between the central wall of the moveable shell portion and the stationary wall of the stationary shell portion.

### Claim 16

A vehicle comprising:
a structure having a hood and defining an engine compartment; and
an air cleaner box assembly attached to the structure and disposed within the engine compartment, the air cleaner box assembly including:
a moveable shell portion having an upper surface disposed adjacent the hood, and defining a filtered air chamber;
a stationary shell portion attached to the structure and defining an unfiltered air chamber;
a filter element attached to and supported by the moveable shell portion, and separating the filtered air chamber and the un-filtered air chamber; and
a plurality of guide members, with each of the plurality of guide members slideably connecting the moveable shell portion and the stationary shell portion for guiding the moveable shell portion along a path relative to the stationary shell portion, between an expanded position, and a compressed position;
wherein the moveable shell portion is moveable relative to the stationary shell portion a maximum distance along the path, and wherein the stationary shell portion provides a free space along the path that does not interfere with the movement of the moveable shell portion.

### Claim 17 (depends on 16)

The vehicle set forth in claim 16, wherein each of the plurality of guide members include a pin fixedly attached to the stationary shell portion, and include a central axis extending substantially parallel with the path of the moveable shell portion.

### Claim 18 (depends on 16)

The vehicle set forth in claim 16, wherein the moveable shell portion includes a first shell portion and a second shell portion removeably attached to the first shell portion, with the filter element clamped in place between the first shell portion and the second shell portion.

### Claim 19

A vehicle comprising:
a structure having a hood and defining an engine compartment; and
an air cleaner box assembly attached to the structure and disposed within the engine compartment, the air cleaner box assembly including:
a moveable shell portion having an upper surface disposed adjacent the hood, and defining a filtered air chamber;
a stationary shell portion attached to the structure and defining an unfiltered air chamber;
a filter element attached to and supported by the moveable shell portion, and separating the filtered air chamber and the un-filtered air chamber;
a plurality of guide members, with each of the plurality of guide members slideably connecting the moveable shell portion and the stationary shell portion for guiding the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position;
wherein each of the plurality of guide members include a pin fixedly attached to the stationary shell portion, and include a central axis extending substantially parallel with the path of the moveable shell portion; and
wherein each of the plurality of guide members include a spring coiled around the pin and disposed between the moveable shell portion and the stationary shell portion, wherein the spring of each of the plurality of guide members bias the moveable shell portion into the expanded position, and yields in response to a force applied to the moveable shell portion to allow movement of the moveable shell portion along the path toward the stationary shell portion and into the compressed position.
