Nozzle assembly for supplying air to inner space of motor car, has nozzle provided with deflecting grid in terms of diffused beam cone, where axial airflow is expanded by deflection during axial inflow of grid

摘要

The assembly (1) has nozzles withdrawing directed spin-free axial airflow (6) of large and smaller penetration depths from two different tubular air ducts (2, 3). The air ducts are arranged at a radial distance to each other. One of the nozzles is designed in terms of axial emission. The other nozzle is provided with a deflecting grid (4) i.e. screen, in terms of diffused beam cone (9). The axial airflow is expanded by deflection during axial inflow of the grid. A radial inner area is provided for one of the ducts. A radial outer portion is provided for the airflow.
