An Electro-Impulse Water Jet

摘要

The operating principles of an electro-impulse water jet are described. In the normal impulse water jet, the water is compressed and ejected through a nozzle by the action of a piston which is actuated by compressed gas; while in the electro-impulse water jet the role of the piston is played by a vapor-gas void which appears as a result of an electrical discharge in the water. The electro-impulse water jet has a number of advantages such as simplicity of design, as well as the absence of moving parts, the ease with which the firing process can be automated, and the rapid firing rate.
