Abstract

An air nozzle for discharging an air flow from an air supply duct of a heating, ventilation or air-conditioning system, in particular in a passenger compartment of a vehicle, composed of a nozzle body and of a receiving element which receives the nozzle body, wherein the receiving element is arranged on the air supply duct, and wherein the nozzle body and/or the receiving element are/is mounted so as to be pivotable about at least one degree of freedom, wherein in the interior of the nozzle body there is arranged a swirl insert which is arranged fixedly and which is connected rigidly to the nozzle body.

First claim

The invention claimed is:

1. An air nozzle for discharging an airstream out of an air feed duct of a heating, ventilation, or air conditioning system into a passenger space of a vehicle, composed of a nozzle body and of a reception element receiving the nozzle body, the reception element being arranged on the air feed duct,
wherein in an inner space of the nozzle body there is arranged a fixedly arranged rigid swirl insert connected to the nozzle body,
wherein the rigid swirl insert has a centrally running core arranged at its center, bounding a central hole through which an air jet flows in a straight line,
wherein a plurality of swirl elements are arranged in a uniformly distributed manner radially around the centrally running core, wherein each swirl element extends from the centrally running core to the nozzle body, wherein air flows in a diffuse flow through the plurality of swirl elements in combination with the air jet flowing through the centrally running core,
wherein the entire nozzle body is mounted continuously adjustably within the reception element via a tenon arrangement formed from two tenons,
wherein the reception element is rotatably mounted in the air feed duct to permit clockwise or counterclockwise rotation about an axis extending through the center of the centrally running core.

2. The air nozzle as claimed in claim 1 , wherein the nozzle body provided with the rigid swirl insert is a structural unit formed in one piece.

3. The air nozzle as claimed in claim 1 , wherein the rigid swirl insert is formed from at least two segmental swirl elements distributed uniformly about a mid-axis, wherein a plurality of flow passages are formed between adjacent swirl elements.

4. The air nozzle as claimed in claim 3 , wherein the swirl elements are designed in the manner of a swirl blade.

5. The air nozzle as claimed in claim 1 , wherein the reception element is designed in the form of a ring and has two oppositely arranged side regions with reception orifices for the tenons.

6. The air nozzle as claimed in claim 1 , wherein the nozzle body has an essentially spherical configuration with flattened pole sides.

7. The air nozzle as claimed in claim 1 , wherein the nozzle body can be pivoted between a neutral position and at least one flow setting.

8. The air nozzle as claimed in claim 1 ,
wherein the nozzle body is formed from a single component.

9. An air nozzle for discharging an airstream out of an air feed duct of a heating, ventilation, or air conditioning system into a passenger space of a vehicle, composed of a nozzle body and of a reception element receiving the nozzle body, the reception element being arranged on the air feed duct,
wherein in an inner space bounded by the nozzle body there is arranged a fixedly arranged rigid swirl insert connected to the nozzle body,
wherein the rigid swirl insert has a centrally running core arranged at its center, bounding a central hole through which an air jet flows in a straight line,
wherein a plurality of swirl elements are arranged in a uniformly distributed manner radially around the centrally running core, wherein each swirl element is connected to the centrally running core and the nozzle body, wherein each swirl element extends from the centrally running core to the nozzle body, wherein air flows in a diffuse flow through the plurality of swirl elements in combination with the air jet flowing through the centrally running core,
wherein the nozzle body, the plurality of swirl elements, and the centrally running core are mounted continuously adjustably within the reception element via a tenon arrangement formed from two tenons connected to the nozzle body,
wherein the reception element is rotatably mounted in the air feed duct to permit clockwise or counterclockwise rotation about an axis extending through the center of the centrally running core.

10. The air nozzle as claimed in claim 9 ,
wherein the nozzle body is formed from a single component.
