Abstract: 1. A flat plate ozone generator comprising a high voltage electrode (4), located centrally between two uniform corona chambers (1,1`), wherein each chamber on one side is delimited from said high voltage electrode by dielectric elements (2, 2`) and opposite said by each second electrodes (3, 3`), wherein each of said second electrodes is an earth electrode constituted by a metal block separately delimiting one of said chambers towards the opposing dielectric, wherein a gas inlet passage (5, 5`) and a gas outlet passage (6, 6`) to the delimited chamber is formed in each metal block, and wherein the high voltage electrode is arranged in direct contact with the dielectrics thereby forming a substantially flat packet. 2. The ozone generator according, to claim 1, wherein each sealed chamber (1, 1`) is delimited by least one endlessly, between the dielectric element (2, 2`) and the earth electrode (3, 3`), extending sealing member (7, 7`). 3. The ozone generator according to claim 2, wherein said sealing member (7, 7`) is constituted of an 0-ring. 4. The ozone generator according to claim 2, wherein said high voltage electrode and said dielectric elements are composed of substantially flat bodies. 5. The ozone generator according to claim 4, which packet is held in place by said earth electrodes exerting pressure on said sealing members. 6. The ozone generator according to claim 2, wherein a recess (13, 13`) is arranged in the respective earth electrode (3, 3`) endlessly extending inside the respective chamber adjacent said sealing member (7, 7`), in which recess said inlet passages (5, 5`) emerge. 7. The ozone generator according to claim 2, wherein a ring (10) of an electrically isolating material is arranged externally of the respective sealing member (7, 7`) to protect against spark-over external of the respective chamber (1, 1`). 8. The ozone generator according to claim 2, wherein said sealing member (7, 7`) extends in an annular shape between the respective dielectric element (2, 2`) and earth electrode (3, 3`), thereby delimiting said respective chamber to the shape of circular discs. 9. The ozone generator according to claim 2, wherein for the respective chamber said inlet passage (5, 5`) emerges in the periphery part of the chamber (1, 1`), close to said sealing member (7, 7`), and wherein said outlet passage emerges centrally in the chamber. 10. The ozone generator according to claim 9, wherein a recess (13, 13`) is formed in said earth electrode in the periphery part of the chamber, extending in a ring concentrically inside said sealing member, in which recess said inlet passage emerges. 11. The ozone generator according to claim 1, wherein the high voltage electrode (4) is formed or arranged as a metallic coating on one or both of the dielectric elements (2, 2`). 12. The ozone generator according claim 1, wherein the high voltage electrode is composed of a metal foil or metal sheet. 13. The ozone generator according to claim 1, wherein respective sealed chamber (1, 1`) is partly formed by a shaped recess (8) in the respective earth electrode (3, 3`). 14. The ozone generator according to claim 1, wherein flow control passages for oxygen gas or gas rich in oxygen and ozone are formed in the inside of respective sealed chamber (1, 1`), adapted to conduct the gas flow in predetermined directions in said chamber. 15. The ozone generator according claim 1, comprising a structure arranged or formed in the respective sealed chamber, which structure is formed to promote the forming of a corona-effect at discharge between the high voltage electrode (4), by the dielectric element (2, 2`), to the earth electrode (3, 3`) in respective chamber (1, 1`). 16. The ozone generator according to claim 15, wherein said structure is formed mainly as a net (9). 17. The ozone generator according to claim 15 or 16, wherein the structure (9) is composed of a separate part arranged in respective sealed chamber (1, 1`). 18. The ozone generator according to claim 15 or 16, wherein the structure (9) in the respective sealed chamber (1, 1`) is a pattern formed in the respective earth electrode (3, 3`).
