Abstract
Abstract A substantially tubular-shaped ozone generator embodying an inner electrode, a coaxial outer electrode surrounding the inner electrode and a tube member formed of dielectric material arranged between the inner electrode and the outer electrode. Within the tube member formed of dielectric material there is arranged a substantially cylindrical core provided at its outer surface with one or a number of substantially helically-shaped grooves extending in the axial direction of the core and forming a throughpass channel for the medium to be ozonized and the ozone which is generated.
