ABSTRACT:
An energy converter for generating high-power pulses includes a housing defining a chamber having an open side; an electrode assembly supported in the chamber; a power supply for applying a voltage to the electrode assembly; a fluid medium accommodated in the housing and being in contact with the electrode assembly for receiving pulses from the electrode assembly; and a diaphragm attached to the housing and closing the open side of the housing for encapsulating the electrode assembly and the fluid medium in the chamber. The diaphragm has an inner surface oriented toward the chamber and is in contact with the fluid medium. The diaphragm further has an outer surface oriented away from the chamber and is arranged for contacting a substance to be comminuted, whereby mechanical pulses transmitted from the fluid medium to the diaphragm are applied by the diaphragm to the substance to be comminuted.
