METHOD AND DEVICE FOR ENRICHING AIR WITH OXYGEN IN BODY OF VEHICLE Russian patent published in 1997 - IPC

FIELD: transport mechanical engineering. SUBSTANCE: device has blower made up as fan 1 connected with branch pipe 3 for sucking air through pipe lines 2, gas distributor 4, regenerator 5 with oxygen for reacting with the carbon dioxide in air, by-passing line 8, and outlet branch pipe 9 connected with the cabin. Gas distributor 4 is provided with inlet branch pipes 10 and two outlet branch pipes 11 and 12 for separating air flows between the latters. One of the outlet branch pipes of hydraulic distributor 4 is in communication with regenerator 5. The other branch pipe is in communication with by-passing line 8 which is connected to the outlet of the regenerator and outlet branch pipe 9. Branch pipe 3 for sucking air is in communication with the car cabin. The device is provided with at least one filter 7 mounted at the exit of the regenerator. EFFECT: enhanced efficiency. 11 cl, 1 dwg
