Abstract

Electric discharge valve device for amplifying electrical oscillations, said valve comprising an electrode assembly consisting of a cathode, a grid, an anode and an auxiliary electrode, the anode consisting of two halves, each of which is provided with a depression that is oriented towards the cathode and has approximately the same width as the cathode, said depressions forming the active anode surface, being arranged on both sides, between the anode parts and the grid, screens whose free edges extend to the proximity of the active anode parts, characterized in that the screens consist of four strips, the location of the active edges thereof being determined by openings in insulating centering members, said edges being located between the edges of the active anode parts and the active surface of the grid.
