Abstract

The present application provides a spark generator for generating pressure. The spark generator comprises: a main device; and a pressure chamber disposed adjacent to the main device, wherein the main device comprises: a circuit for generating a predetermined spark voltage; and an electromagnet, wherein the pressure chamber comprises: a non-compressive fluid contained therein; a fixed electrode disposed in the non-compressive fluid; a movable electrode disposed in the non-compressive fluid and separated from the fixed electrode at a predetermined distance; and a permanent magnet disposed on the movable electrode, wherein the circuit is configured to apply the spark voltage between the movable electrode and the fixed electrode, wherein the electromagnet is configured to apply a magnetic force to the permanent magnet to move the movable electrode toward the fixed electrode for generating spark between the movable electrode and the fixed electrode, wherein the pressure chamber comprises a pressure transferring structure composing a part of a wall of the pressure chamber and configured to transfer a pressure of the non-compressive fluid generated by the spark to outside of the pressure chamber.
