GAS ENRICHING DEVICE AND BLOWER WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas enriching device capable of stably securing a desirable supply quantity of the enriched air by considering temperature characteristic of a permeation membrane of a gas enriching device. SOLUTION: This gas enriching device is provided with an oxygen enrichment membrane 2a as a selective gas permeation membrane for selectively permeating a specified gas, a variable capacity pump 3 for generating a pressure difference on a side for permeating the specified gas to carry the oxygen-enriched air, and a temperature detecting sensor 5 for detecting temperature near the oxygen enrichment membrane. Operation capacity of the pump 3 can be changed on the basis of the temperature detected by the temperature detecting sensor 5. COPYRIGHT: (C)2004,JPO
