ABSTRACT:
In a closed discharge chamber wherein a discharge electrode supported on an electric insulating material and an opposite electrode are arranged to confront each other, a high electric potential applied between said electrodes causes corona discharge to occur in the gas between the two electrodes. A method for control of pure fluid elements, fluid servomechanisms, etc. is disclosed which is accomplished by utilizing a phenomenon that the pressure of the gas within the closed discharge chamber increases in consequence of the occurrence of corona discharge and the increased pressure falls with the subsequent extinction of corona discharge back to the level existing before said corona discharge.
