Abstract
An ozone generator comprises a pair of spaced opposing electrodes, electrically conductive members connecting the pair of electrodes to a high-voltage alternating-current power source to generate an electric discharge between the electrodes, a dielectric provided between the opposing electrodes, and a gas flow passage for effecting flow of a material gas defined by the surfaces of the electrodes. At least one of the surfaces of the pair of electrodes has a plurality of parallel grooves. The material gas flows in a space between the plurality of grooves and the dielectric, in a direction transverse to the grooves.

An ozone generator comprising:
- a pair of electrodes provided in spaced opposing relation;
- electrically conductive members adapted to connect said pair of electrodes to a power source for applying a voltage between said pair of electrodes and generating an electric discharge between the electrodes;
- a dielectric provided between said spaced opposing electrodes;
- and
- a gas flow passage for effecting flow of a material gas between said spaced opposing electrodes,
- wherein at least one of the electrodes has a surface including a plurality of grooves, and the material gas flows in a space defined between the plurality of grooves and the dielectric, in a direction transverse to the grooves.
An electric discharge cell for an ozone generator, comprising:
- a pair of electrodes provided in spaced opposing relation, with each of the electrodes having surfaces which are generally circular in form;
- electrically conductive members adapted to connect said pair of electrodes to a power source;
- and
- a gas flow passage for effecting flow of a material gas defined by the surfaces of said opposing electrodes,
- wherein one of said surfaces is covered by a flat dielectric plate, and the other of said surfaces includes a plurality of concentric or generally concentric circular grooves, and wherein the material gas is caused to flow in a direction transverse to said plurality of grooves.
