Abstract

An air intake device for a vehicle. The device includes an inlet for air, a first outlet arranged for providing air to an engine of the vehicle and a second outlet arranged for discharging liquid separated from the air provided to the first outlet, and an intermediate portion forming an air channel extending from the inlet to the first outlet and the second outlet. A bottom surface on the inside of the intermediate portion is inclined relative to a horizontal plane for directing liquid in the air channel towards the second outlet.

First claim

What is claimed is:

1. An air intake device for a vehicle, the device comprising:
an inlet through which air is received into the air intake device,
a first outlet through which air is discharged toward an engine of the vehicle,
a second outlet through which liquid that has been separated from the air is discharged, and
an intermediate portion forming an air channel extending in an airflow direction from the inlet to the first outlet and to the second outlet, wherein the air channel comprises a bottom surface formed by a lower wall of the intermediate portion and,
wherein the bottom surface of the air channel is inclined relative to a horizontal plane for directing liquid in the air channel towards the second outlet and away from the first outlet, the bottom surface including:
a first bottom surface portion extending from the first outlet along the intermediate portion toward the air intake at an upward inclination relative to the horizontal plane in the airflow direction from the inlet to the first outlet; and
a second bottom surface portion extending from the second outlet along the intermediate portion toward the air intake at a downward inclination relative to the horizontal plane in the airflow direction from the inlet to the second outlet, and wherein, relative to the airflow direction, the first bottom surface and the second bottom surface portion are laterally adjacent to each other.

2. The device according to claim 1 , wherein the first bottom surface portion and the second bottom surface portion are further inclined relative to the horizontal plane in a direction perpendicular to the airflow direction so that the bottom surface is higher in elevation along the first bottom surface portion than along the second bottom surface portion.

3. The device according to claim 2 , wherein the bottom surface has a downward slope in a direction from the first outlet to the second outlet.

4. The device according to claim 2 , wherein the inclination in the direction perpendicular to the airflow direction is different along the first bottom surface portion than along the second bottom surface portion.

5. The device according to claim 2 , wherein the first bottom surface portion and the second bottom surface portion are connected by a threshold step that provides an increase in elevation to the first bottom surface portion relative the second bottom surface portion.

6. The device according to claim 1 , wherein the intermediate portion has a bend portion making the air channel curved.

7. The device according to claim 1 , wherein the first bottom surface portion and the second bottom surface portion are arranged laterally side by side in the bend portion, the first bottom surface portion arranged along an inner curve of the bend portion and the second bottom surface portion arranged along an outer curve of the bend portion.

8. The device according to claim 1 , wherein the first outlet and the first bottom surface portion are connected by a threshold step such that the first outlet is higher in elevation than the first bottom surface portion.

9. A vehicle comprising the air intake device according to claim 1 .

10. A device according to claim 1 , wherein, relative to the airflow direction, the first outlet and the second outlet are laterally adjacent to each other.
