うにしたものがあげられる。An example of a pressure fluctuation adsorption type oxygen concentrator, which is a preferred embodiment of the device of the present invention, will be described in more detail. That is, in addition to a compressor and a blower, it is equipped with two adsorption beds filled with an adsorbent that selectively adsorbs nitrogen, and a storage tank that temporarily stores the oxygen-enriched gas discharged from the adsorbent. There are conduit means connecting the compressor and each adsorption bed via a three-way automatic switching valve for flow path switching, conduit means connecting the adsorption bed and storage tank via each automatic on-off valve, and oxygen from the storage tank. Conduit means for making the concentrated gas available for use, conduit means for connecting the two discharge sides to equalize the pressure via an automatic pressure equalization valve, and increasing the concentration of nitrogen from the inlet side of each adsorption bed. Examples include those equipped with a conduit means that automatically opens and closes to discharge the trapped gas. The operating mode of this equipment is to perform an adsorption process in which compressed air is supplied to one adsorption bed to adsorb nitrogen and discharge oxygen-enriched gas with a concentration of approximately 90%, followed by a pressure equalization automatic on-off valve. The oxygen-enriched gas is allowed to flow from one adsorption bed into the pond bed, where desorption has already been completed, to equalize the pressure.Then, the automatic discharge valve is opened to release the residual gas, and the remaining gas is discharged to the storage tank. A series of cycles are alternately performed in which the desorption process is performed by backflow purging with oxygen-enriched gas. The conduit means for use is equipped with a pressure reducing control valve, flow rate setting means, etc. A specific example of such a flow rate setting means is one in which a plate having a plurality of openings with different opening areas is used, and the opening is selected and used according to the flow rate to be used.
