Abstract Device for the production of ozone from oxidized gases by means of silent electrical discharge in an intermediate chamber through which said gas has passed, which chamber is formed by an annular external electrode and a voltage-conducting internal electrode which is surrounded concentrically by said external electrode. A dielectric is arranged between the internal and the external electrode. In order to increase the degree of efficiency of such a device and, at the same time, to enable utilization of lower voltages, the internal electrode consists of a polygonal bar or polygonal tube having more than four longitudinal edges. The ratio of the diameter of the external electrode to the largest diameter of the internal electrode is not greater than two.
