<p>PURPOSE: To provide a pressure swing type oxygen enriching device for vehicles which is easily mountable at the vehicle and features high operating efficiency. CONSTITUTION: The pressure swing type oxygen enriching device having adsorption cylinders 2-A, 2-B packed with adsorbents 1, a four-way solenoid valve 3 for changing over the flow of compressed air, etc., thereto and a controller 7 is mounted at the vehicle. The device is provided with a pressurizing pipe 15 in such a manner that the device receives the supply of the compressed air from a compressed air device 60 equipped in the vehicle for the purpose of a compressed air utilizing device 70, such as air brake, as a raw material of the concn. gaseous oxygen of the device. A throttle 90 is disposed between the pressurizing pipe parts 15-(a) and 15-(b) constituting the pressurizing pipe 15 to prevent the flow of the excess air to the adsorption cylinders in the state of a large pressure difference between the adsorption cylinders where the adsorption storoke just begins and an air compressor 60.</p> |
