DEVICE FOR ELECTROHYDRAULIC CRUSHING OF HARD BODIES Russian patent published in 1995 - IPC

FIELD: building industry. SUBSTANCE: device has a housing made in the form of a thin-wall metal cup, dielectric cylindrical bushing located inside the housing, electric insulator mounted on the open end of the housing to form a closed, water filled space inside. One electrode is fitted into the hole made in the insulator, the other is fastened on the lower part of the housing. The electrodes are shaped like bushings located coaxially to the housing and connected between each other by a thin wire hermetically fastened on their external ends. There is a high-voltage pulses generator connected to the tied electrode and housing. EFFECT: higher efficiency and reliability. 4 cl, 1 dwg
