Abstract
The invention relates to an air vent (1), especially for a motor vehicle, comprising an air channel for supplying air, and an air guiding device (4). The air channel is divided into at least two essentially cylindrical partial channels (11a, 11b) in the air guiding device (4), said cylindrical partial channels (11a, 11b) being parallel to each other. Especially other partial channels (12a, 12b) provided in the inventive air vent generate a swirling flow.
Claims19
An air vent, especially for a motor vehicle, with an air-supplying air duct and with an air conduction device, the air duct in the air conduction device being divided into at least two essentially cylindrical subducts, wherein the cylindrical subducts are arranged parallel with respect to one another, wherein at least one further subduct is provided, arranged around at least one of the cylindrical subducts, and wherein, upstream of the air conduction device, a metering device is arranged, which is designed in such a way that the air capable of being supplied to the individual subducts is controllable.
An air vent, especially for a motor vehicle, with an air-supplying air duct and with an air conduction device, the air duct in the air conduction device being divided into at least two essentially cylindrical subducts, wherein the cylindrical subducts are arranged parallel with respect to one another, wherein at least one further subduct is provided, arranged around at least one of the cylindrical subducts, and wherein the ratio of a narrowest cross section of one of the cylindrical subducts to the narrowest cross section of the at least one further subduct is variable from 1:1.5 to 1:0.3.
An air vent, especially for a motor vehicle, with an air-supplying air duct and with an air conduction device, the air duct in the air conduction device being divided into at least two essentially cylindrical subducts, wherein the cylindrical subducts are arranged parallel with respect to one another, wherein at least one further subduct is provided, arranged around at least one of the cylindrical subducts, and wherein each cylindrical subduct has arranged around it at least two helical subducts which can be regulated independently of one another via separate control devices.
An air vent, especially for a motor vehicle, with an air-supplying air duct and with an air conduction device, the air duct in the air conduction device being divided into at least two essentially cylindrical subducts, wherein the cylindrical subducts are arranged parallel with respect to one another, wherein at least one further subduct is provided, arranged around at least one of the cylindrical subducts, wherein the air vent has a lamellar air conduction device, and wherein the lamellar air conduction device is of centrally divided design, and the two parts can be regulated independently of one another.
A method for controlling the air outflow of an air vent especially for a motor vehicle, with an air-supplying air duct and with an air conduction device, the air duct in the air conduction device being divided into at least two essentially cylindrical subducts, wherein the cylindrical subducts are arranged parallel with respect to one another, wherein at least one further subduct is provided, arranged around at least one of the cylindrical subducts, and wherein a first metering device or flap of at least one first air duct and a second metering device or flap of at least one second air duct are alternately opened and closed.
