<P>PROBLEM TO BE SOLVED: To provide an oxygen supplying device for a working medium circulation type engine capable of improving responsiveness during the transient operation of an engine output. Ž<P>SOLUTION: The oxygen supplying device 30 for the working medium circulation type engine includes: a plurality of combustion chambers CC in which working mediums having higher ratios of specific heat than air are expanded accompanied by the combustion of oxygen and hydrogen; and a circulation path including a plurality of intake air branch passages 17a communicating with the plurality of combustion chambers CC, circulating the working mediums from exhaust sides of the combustion chambers CC to the intake side thereof, and resupplying the working mediums to the combustion chambers CC through the intake air branch passages 17a. In the device, an oxygen supply chamber 35 supplied with oxygen is provided, a plurality of supply ports 36 communicating with the oxygen supply chamber 35 are formed for supplying oxygen in the oxygen supply chamber 35 to the plurality of intake air branch passages 17a, and a regulation means 32 is provided for regulating the amount of oxygen supplied from the supply ports 36 by regulating pressure in the oxygen supply chamber 35.
