Abstract
An air outlet nozzle of a heating and/or air-conditioning system of a vehicle is provided. It has a displacer which is connected to a nozzle mouth element mounted displaceably in the nozzle housing. In order, with as little structural space as possible and as little flow losses as possible, to be able to control the diffusivity of the air jet emerging from the air outlet nozzle, the flow resistance and the axial position of the displacer can be adjusted.
Claims33
An air outlet nozzle for a ventilation system, comprising:
- a nozzle housing which has an outlet mouth,
- a nozzle mouth element, and
- a displacer which is arranged in an airflow in a mouth region and is connected to the nozzle mouth element,
- wherein a position of the displacer is settable in an axial direction relative to the outlet mouth by the displacer being displaceable from a position in the outlet mouth into a position outside the nozzle housing, and
- wherein the displacer has an adjustable flow obstruction which is lesser in the position in the outlet mouth.
An air nozzle for vehicle ventilation, comprising:
- a nozzle housing having an outlet,
- an outlet element, and
- a displaceable obstruction being arranged in an airflow path in a region of the outlet and connected to the outlet element, the obstruction being displaceable in an axial direction of the outlet to a position outside the nozzle housing from a position of the outlet, the obstruction providing an adjustable flow obstruction which is lesser in the position of the outlet.
A method of making an air outlet nozzle for a ventilation system of a vehicle, comprising:
- providing a nozzle housing with an outlet mouth, arranging a displacer in an operable air flow path in a mouth region, and
- connecting the displacer to a nozzle mouth element so that a position of the displacer can be set in an axial direction relative to the outlet mouth by the displacer being displaceable from a position in the outlet mouth into a position outside the nozzle housing in use, wherein the displacer has an adjustable flow obstruction which is lesser in the position in the outlet mouth.
