For the oxygen enrichment of air two containers (11,11′) working according to a pressure change process are provided. Each container (11, 11′) is partly filled with a packed zeolite bed (13, 13′). Compressed air is fed to one container via a common closure device (41). At a certain pressure value a chamber (27) disposed in the container. (11) opens, with oxygen-enriched air flowing into the chamber. The oxygen-enriched air leaves the container (11) via an ascending pipe (37) and can be used as combustion air in internal combustion engines or the like. The one container (11) adsorbs the nitrogen from the compressed air through its packed zeolite bed (13), while the other container (11′), the chamber of which is closed, is desorbed. An oscillation generator (25) can be used to cause the packed zeolite beds (13, 13′) to oscillate at high frequency and in this way to increase the adsorbing capacity and to accelerate the desorption process.

An apparatus for the oxygen enrichment of air, with at least one container (11) holding a packed zeolite bed (13) and having a container inlet (15) for compressed air, a container outlet (23) for oxygen-enriched air, a container inlet (15) for scavenging air and a container outlet (19) for nitrogen, characterized in that the container (11) includes a separate chamber (27) capable of being opened and gastightly closed relative to the interior of the container (11) by means of the internal container pressure and comprising an upper and a lower portion (31, 33) separable from one another by the internal container pressure, thus producing an annular gap as a chamber inlet (17) said chamber (27) having a chamber outlet (29) connected to the container outlet (23).
