PURPOSE: An adsorption type oxygen generator which is more simply constructed and increases durability by using a rotation valve is provided. CONSTITUTION: The oxygen generator comprises a plurality of adsorption pipes(10) for extracting oxygen from air that is sucked in; a compressor(20) for supplying the compressed air into the adsorption pipes(10) by compressing air in the atmosphere; a plurality of orifices(40) for discharging oxygen to a storage tank according to pressure of the plurality of adsorption pipes(10); and a rotation valve(30) comprising a housing(31) that is connected to the compressor(20) and the adsorption pipes(10) to connect moving of gas, and an operating body(34) that is closely adhered to the housing(31) to control distribution of gas; and a motor(50) for rotating the operating body(34), wherein the housing(31) comprises a compressed air supply port(32) that is formed on the center of the housing(31) and connected to the compressor(20), and a plurality of gas entrances(33) that are formed at one side of the compressed air supply port(32) with spaced apart from each other in a constant rotational distance and connected to the plurality of adsorption pipes(10), and the operating body(34) comprises a compressed air distribution groove(35) that is opened in such a way that the compressed air supply port(32) and at least one or more of the gas entrances(33) are opened, and a gas discharge groove(36) that is formed in such a way that at least one or more of the gas entrances(33) are opened and connected to the outside.
