An air vent for a vehicle interior ventilation system including a diffuse air flow duct with a diffuse outlet opening for discharging the air as a diffuse or swirling jet, a movable connecting sleeve with an inflow opening and an outflow opening as a spot outlet opening, which forms a spot air flow duct at a spot outlet opening. Through movement of the connecting sleeve, different discharge directions of the spot jet from the spot outlet opening can be adjusted. The air discharged through the connecting sleeve is redirectable substantially completely in different discharge directions with pivoting of the connecting sleeve. The connecting sleeve has a greater cross-sectional area at the inflow opening than at the outflow opening and at least one air guiding wall is formed in the connecting sleeve.

An air vent for a vehicle interior ventilation system, the air vent comprising: at least one diffuse air flow duct with at least one diffuse outlet opening configured to discharge air as a diffuse or swirling jet;at least one spot air flow duct with at least one spot outlet opening configured to discharge the air as a spot jet; andat least one movable connecting sleeve with an inflow opening and an outflow opening configured as a spot outlet opening, the at least one connecting sleeve forming the at least one spot air flow duct at the at least one spot outlet opening, and via movement of the at least one connecting sleeve, different outflow directions of the spot jet from the at least one spot outlet opening is adjusted,wherein, the at least one connecting sleeve has a greater cross-sectional area at the inflow opening than the outflow opening and at least one air guiding wall is formed in the at least one connecting sleeve. 2. The air vent according to claim 1, wherein the at least one connecting sleeve has a conical shape with a cross-sectional area that becomes smaller in the air flow direction. 3. The air vent according to claim 1, wherein the at least one connecting sleeve has a greater width and a greater height at the inflow opening than at the outflow opening. 4. The air vent according to claim 1, wherein the at least one connecting sleeve is pivotable. 5. The air vent according to claim 1, wherein the at least one air guiding wall is directed substantially parallel to an axis of the at least one connecting sleeve or an air flow direction in the at least one connecting sleeve. 6. The air vent according to claim 1, wherein the at least one air guiding wall is formed completely continuous within the flow space of the at least one connecting sleeve, so that the at least one air guiding wall divides the flow space within the at least one connecting sleeve into at least two separate partial flow compartments. 7. The air vent according to claim 1, wherein the at least one air guiding wall is formed as a center wall in the at least one connecting sleeve so that the center wall divides the flow space within the at least one connecting sleeve into only two totally separate, substantially equally large partial flow compartments. 8. The air vent according to claim 1, wherein a swirl generator is arranged in the flow direction upstream of the at least one connecting sleeve. 9. The air vent according to claim 1, wherein the at least one connecting sleeve is arranged within the at least one diffuse air flow duct and the air vent comprises a housing and wherein the at least one connecting sleeve is arranged within the housing and the at least one diffuse air flow duct is bounded by the housing. 10. A motor vehicle HVAC system, wherein the motor vehicle HVAC system comprises at least one air vent according to claim 1. 11. The air vent according to claim 1, wherein the cross sectional area of the inflow opening is 5-30% greater than the cross sectional area of the outflow opening. 12. The air vent according to claim 1, wherein the at least one air guiding wall is formed as a completely flat, vertical surface. 13. The air vent according to claim 7, wherein the center wall divides the flow space such that air does not flow from one flow compartment to another flow compartment.
