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.

Abstract: An air vent having a housing, a first control element and a second control element, wherein the housing forms a flow passage, wherein the first control element is supported on the housing so as to be rotatable about a first axis of rotation and the second control element is supported on the housing so as to be rotatable about a second axis of rotation, wherein the second axis of rotation is perpendicular to the first axis of rotation, wherein the first control element is connected to the second control element by a coupling element and the control elements are movable relative to one another.
