Abstract (en)
[origin: JPH04235763A] PURPOSE: To miniaturize and lighten an electrostatic spray gun by providing a carrier plate of sintered ceramic that is printed with interconnects and capacitor electrodes to print the diodes of the high-voltage cascade onto a corresponding carrier plate in the integrated or attached high-voltage cascade. CONSTITUTION: In an electrostatic spray gun, particularly a hand spray gun for coating workpieces with liquid or powdery coating material, an integrated or attached high-voltage cascade is provided with a carrier plate 10 of sintered ceramic that is printed with interconnects 12 and capacitor electrodes 11. The diodes of the high-voltage cascade can also be printed onto a corresponding carrier plate. As a result, the dimensions of the electrostatic spray gun can be remarkably diminished and the weight can be considerably reduced.
