An air outlet device for a vehicle, especially for an aircraft, comprises a nozzle body with an air intake opening and an air outlet opening. The air outlet device further comprises a holding element formed with an accommodating opening having the nozzle body supported therein for rotation about a longitudinal axis extending through the air intake opening and the air outlet opening, and a valve body arranged coaxially within the nozzle body and guided by the holding element. Upon rotation of the nozzle body, the valve body can be displaced in the nozzle body between a closing position for blocking the air outlet opening and a maximum opening position for clearing the air outlet opening to the maximum extent. The valve body is of a hollow configuration.

The present invention relates to an air outlet device for a vehicle.
As a common feature in vehicles, particularly in airplanes and busses, it is provided that each passenger can set a cooling air stream individually for his or her convenience by means of an air discharge nozzle arranged in the ceiling above the seat. Such air outlet devices (“air showers”) comprise a nozzle body to be selectively closed and set to different spatial configurations so that the discharged air stream can be oriented correspondingly.
An air outlet device of the above type is known e.g. from U.S. Pat. No. 5,399,119. This air outlet device comprises a nozzle body with an air intake opening and an air outlet opening. Arranged within the nozzle body is a coaxial valve body which, by turning the nozzle body, can be displaced between a closed position for closing the air outlet opening and one of several opening positions arranged to open the air outlet opening to a higher or lesser extent. The nozzle body is supported for rotation on a holding element, which in turn is supported in a holding recess formed in a ceiling panel above the seat.
FIG. 1 is a lateral view of the air outlet device for air supply towards a seat in a vehicle, such as e.g. an aircraft or bus, with the paneling on the ceiling schematically outlined;
FIG. 2 is a sectional view taken along the line II—II in FIG. 1;
FIG. 3 is a sectional view taken along the line III—III in FIG. 2; and
FIGS. 1 to 4 illustrate the configuration of an air outlet device 10 and the cooperation of the various components of the device 10. According to FIG. 1, the air outlet device 10 is arranged in the ceiling paneling 12 above a passenger seat e.g. of an airplane or bus. By manual operation of the air outlet device 10, the intensity and the direction of a discharged air flow can be changed.
The air outlet device 10 comprises a spherical holding element 14 arranged in a cylindrical accommodating element 16 to be pivoted in element 16 within a spatial angle dictated by the constructional design. This accommodating element 16 is shaped after the manner of a shell and on its end adjacent the ceiling paneling 12 is provided with an inner flange 18 (cf. FIG. 2) abutting the spherical outer side of spherical holding element 14. The spherical holding element 14 is inserted, from the end of accommodating element 16 opposite the inner flange 18, into a support element 20. The outer side of support element 20, abutting the accommodating element 16, is cylindrical, and the side of support element 20 abutting the holding element 14 is spherically concave. Support element 20 does not only serve for support of spherical holding element 14 but also for effecting an air-tight closure of the space between accommodating element 16 and holding element 14. In its mounting position shown in FIG. 2, support element 20 is biased by a corrugated spring ring 22 supported on support element 20 and on a retaining ring 24 secured on the accommodating element 16.
As shown in FIG. 1, the accommodating element 16 is arranged in a chamber or shaft 26 supplied with pressurized air and, by its end provided with the inner flange 18, is arranged in sealing abutment on the edge 28 of an opening 30 of the ceiling paneling 12. Thus, a part of the spherical holding element 14 and an operating member for setting the intensity and the direction of the air flow will project from opening 30.
