Abstract

Improvements in devices for spark erosion machines, whose working gap can be coupled to a source of direct current impulses for the creation of work pulses with an appropriate separation of the impulses, constituted by an accumulation device that can function in a stepped to the beat of control pulses, it can be coupled to the working gap and contains a capacitor, which accumulator capacitor can be charged by impulse from the voltage of the working gap up to a signal voltage and can be discharged by means of a device regulation to an extinction voltage, the voltage of the signal can be extinguished in this device stepwise by means of a regulation device and then be formed again.
