    摘要： An electrode adapted for use in an electrohydraulic system in which kinetic forces are developed by means of a submerged electrical discharge. An elongated electrode extends axially toward a body of hydraulic fluid and axially through a chamber defined by an annular conducting member and a generally conical insulator. A plurality of arc-initiating members extend radially inwardly from the annular member. The elongated electrode includes a first arc-initiating enlargement and a second, axially-spaced enlargement which acts as a shield for the insulator, the enlargements being disposed axially at opposite sides of the arc-initiating electrodes.
