Patent ID: 8113195

Claim:
A combination of an aircraft cabin and a device for supplying a free-jet to the visual field of a user in the aircraft cabin, wherein the device comprises: a line; an outlet nozzle located within the aircraft cabin; a transport unit; an additional line; an additional outlet nozzle; an additional transport unit; and a storage tank of an oxygen-containing component and a container of a water-containing component, the oxygen-containing component and the water-containing component being suppliable to the line and the additional line; wherein a mixture of the oxygen-containing component and the water-containing component is transportable by the transport unit through the line to the outlet nozzle, so that the mixture streams through the outlet nozzle in the form of a free-jet directly toward the visual field of the user such that the free-jet is supplied to the visual field with an injection jet axis speed of at least 0.5 meters per second (m/s) to increase oxygen concentration and atmospheric humidity at the visual field; wherein a mixture of the oxygen-containing component and the water-containing component is transportable by the additional transport unit through the additional line to the additional outlet nozzle, so that the mixture streams through the additional outlet nozzle directly toward the visual field of another user; wherein the device is adapted in such a way that the mixture exiting the outlet nozzle is supersaturated, so that the water-containing component at least partially condenses after the mixture has exited the outlet nozzle, the free-jet not being guided by a conduit between the outlet nozzle and the visual field of the user, and wherein the device is arranged behind a wall of the aircraft cabin such that only the outlet nozzle protrudes from the wall, the wall being a lateral wall or a ceiling wall of the aircraft cabin.
