Abstract
Abstract In an ozone generator composed of a plurality of circular, plate-shaped high-voltage electrodes arranged in a stack, the electrodes including at least two solid electrodes which are spaced from one another and a counter-electrode, the generator further being composed of two circular plates of insulating material disposed in the stack between the two solid electrodes, with the counter-electrode being disposed between, and spaced from, the two plates to form therewith two discharge spaces, and with the outer diameter of the counter-electrodes being less than that of the plates, and a ring clamped and squeezed between the plates in the vicinity of their peripheries, the ring is of a gasket material which is initially resilient, and which is formed to have, at each side directed toward a respective plate, at least two beads projecting in the axial direction of the plates and spaced apart in the radial direction of the plates, and the plates are rigidly supported against the two solid electrodes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
In an ozone generator composed of a plurality of circular, plate-shaped high-voltage electrodes arranged in a stack, the electrodes including at least two solid electrodes which are spaced from one another and a counter-electrode, the generator further being composed of two circular plates of insulating material disposed in the stack between the two solid electrodes, with the counter-electrode being disposed between, and spaced from, the two plates to form therewith two discharge spaces, and with the outer diameter of the counter-electrode being less than that of the plates, and a ring clamped and squeezed between the plates in the vicinity of their peripheries, the improvement wherein said ring is of a gasket material which is initially resilient and which is selected for increasing the dielectric strength, and inhibiting electrical break-down, in the radial direction of said circular plates between the periphery of said counter-electrode and said solid electrodes, and wherein said plates are rigidly supported against said two solid electrodes.
Claim 2
Dependent Claim
160 words
In an ozone generator composed of a plurality of circular, plate-shaped high-voltage electrodes arranged in a stack, the electrodes including at least two solid electrodes which are spaced from one another and a counter-electrode, the generator further being composed of two circular plates of insulating material disposed in the stack between the two solid electrodes, with the counter-electrode being disposed between, and spaced from, the two plates to form therewith two discharge spaces, and with the outer diameter of the counter-electrode being less than that of the plates, and a ring clamped and squeezed between the plates in the vicinity of their peripheries, the improvement wherein said ring is of a gasket material which is initially resilient and which is selected for increasing the dielectric strength, and inhibiting electrical break-down, in the radial direction of said circular plates between the periphery of said counter-electrode and said solid electrodes, and wherein said plates are rigidly supported against said two solid electrodes.
Claim 3
Dependent Claim
43 words
Ozone generator according to claim 1, wherein said ring is formed to have, at each side directed toward a respective plate, at least two beads projecting in the axial direction of said plates and spaced apart in the radial direction of said plates.
Claim 4
Dependent Claim
95 words
Ozone generator according to claim 1, wherein said solid electrodes are flat plates without joints, and further comprising: a spacer ring of a rigid plastic interposed between said solid electrodes, at the peripheries thereof; sealing rings inserted into said spacer ring for forming a seal between said spacer ring and each said solid electrode; and a conductive pin having pointed ends, said pin extending through said spacer ring in the axial direction of said solid electrodes and penetrating, with their pointed ends, into said solid electrodes for effecting an equipotential connection between said solid electrodes.
Claim 5
Dependent Claim
21 words
Ozone generator according to claim 1 in combination with a casing filled with water, said generator being immersed in the water.
Claim 6
Dependent Claim
30 words
Ozone generator according to claim 4 further comprising clamping means pressing said solid electrodes and said plates together and tightly clamping said ring between said plates for compressing said ring.
Claim 7
Dependent Claim
30 words
Ozone generator according to claim 1 further comprising clamping means pressing said solid electrodes and said plates together and tightly clamping said ring between said plates for compressing said ring.
