Vehicle air vent

Abstract

Vehicle Air Vent The invention relates to an air vent (10) comprising: a ventilation duct (12) extending along a principal axis (20) and defined by a first internal surface (22); - an outlet portion (14), defined by a second internal surface (30), continuous with the first internal surface (22) of the duct; - a central element (16), disposed in the duct along the principal axis; and - a plurality of longitudinal walls (17, 117, 217) disposed in the duct, parallel to the principal axis; each longitudinal wall extending radially between the central element (16) and the first internal surface (22) of the duct; the central element and the longitudinal walls being fixed relative to the duct. The second internal surface (30) has a transverse dimension (24, 34) decreasing from the first internal surface (22) of the duct. Figure for the abstract: Figure 2

Claims

5. Aerator according to claim 4 taken in combination with claim 2, wherein the first (a) and second (|3) angles are substantially equal.

6. Aerator according to any one of the preceding claims, further comprising a deflector disposed in the outlet portion, the deflector comprising an annular wall disposed around the main axis, the annular wall having a frustoconical shape and forming a fourth angle (0), between 30° and 60°, with the main axis.

7. Aerator according to claim 6 taken in combination with claim 2, wherein the first (a) and fourth (0) angles are substantially equal.

8. Aerator according to any one of claims 6 or 7, wherein: - the outlet portion (14) comprises an open downstream end (32), defining an outlet of the aerator; - the aerator comprises: a first free jet zone (64), defined as a projection of a first annular volume, included between the central element (16) and the deflector (18); and / or a second free jet zone, defined as a projection of a second annular volume, included between the deflector (18) and the downstream end (32) of the outlet portion; and - the aerator is configured such that a sum of the first (64) and second free jet zones is less than or equal to 5% of an area defined by the downstream end (32) of the outlet zone (14).

9. Aerator according to any one of the preceding claims, wherein the plurality of longitudinal walls (17, 117, 217) delimits a plurality of distinct channels (46, 146).

10. Ventilation assembly, comprising: an aerator (10) according to claim 9; and at least one air supply element (66, 166) for the various channels, said at least one supply element being arranged in the aerator (10) or in air supply ducts to the aerator. 36 40 38
