ELECTRIC DISCHARGE IMPACT DEVICE Russian patent published in 2008 - IPC E21C37/18 

FIELD: electricity.

SUBSTANCE: invention is related to the field of processing or destruction of materials with application of electric charge energy in condensed mediums, in particular, for destruction of rocks, making openings in wall panels, perforation of metal items, etc. Electric discharge impact device contains guide cylinder with manipulation control handles, inside of which balloon and piston with discharger are installed with the possibility of reciprocal motion. Discharger is connected to source of power supply. Balloon consists of cylindrical piston and rod striker made as a whole, which have section in the form of truncated cone. Surface of cone is described with function of exponential type. Cavity is arranged in the piston, and its profile is determined by revolution body of function y(x) = xe^-(x+a)/b (dcos² ((x-c)/c)+n), where a, b, d, c, n - coefficients, which is filled with liquid. Through opening is provided in the end of cylindrical piston, where electrode in the form of rod is coaxially installed with clearance. On the opposite side in the cavity electrode is provided in the form of cone, at that length of discharge gap is less than value of argument x, which corresponds to maximum of function y(x). Invention makes it possible to most efficiently and purposefully use energy of electric charge in condensed medium, to increase value of efficiency factor and to expand technical possibilities of application.

EFFECT: increase of efficiency factor value and expansion of technical possibilities of impact device application.
