ABSTRACT:
A device for enriching air with oxygen in an aircraft, and a method for operating the device provides product gas enrichment with oxygen with minimum requirements. An oxygen measurement apparatus analyzing the product gas flow as well as a throughput sensor are provided in combination with a change-over device. A flow connection to an outlet channel is created in a first switch position, and a flow connection to a consumer conduit exists in a second switch position. A device for producing a change-over signal from the first switch position to the second switch position is provided if the determined oxygen output as a product of the product gas flow and the oxygen concentration has reached or exceeded a predefined threshold value.
