1. An ozone generator for generating ozone comprising at least one high voltage electrode (HVE), a first electrode, having a first HVE surface, an opposite second HVE surface;
two low voltage electrodes (LVE), a first LVE and a second LVE each comprising a first LVE surface and an opposite second LVE surface, said HVE(s) is/are placed in a region between the LVE;
at least one dielectric and an electric isolator placed in an area between the two LVE;
an inlet gas port for leading oxygen rich gas into the generator and an outlet gas port for leading generated ozone gas out of the generator;
a first gap and a second gap and at least one of the gaps being a corona chamber that at least one dielectric comprising a first surface is turning towards the first HVE-surface and an opposite second surface is turning towards the first LVE surface of one of the LVE, at least one of the gaps is placed between the first surface of said dielectric and the first HVE-surface, the at least of the gaps being a corona-chamber adapted to develop ozone and that the oxygen is led through the inlet gas port to a duct ending in a center portion of one of the gaps;
the second surface of the dielectric is directly or indirectly supported in its full extension by the first LVE-surface, and the isolator has a plurality of communication holes placed in a distance from a center of the isolator and the communication holes being in fluid communication with the duct; and
said communication holes are fluidly connecting the two gaps, whereby gas is allowed to flow from the gap being in fluid communication with the inlet gas port to the opposite placed gap being in fluid communication with the outlet gas port.
