Ultra-high pressure generator

Abstract

An ultra-high pressure generator includes: an intensifier that discharges pressurized fluid and has a double-acting drive cylinder formed to have a first chamber and a second chamber which are delimited by a piston driven by a working medium, high pressure cylinders which discharge the pressurized fluid, and plungers which reciprocate with the piston in the high pressure cylinders; a closed-circuit working medium pump having a first and second ports as suction/discharge ports for the working medium; a drive source that drives the closed-circuit working medium pump; a first working medium channel that communicates the first chamber with the first port; and a second working medium channel that communicates the second chamber with the second port, wherein the closed-circuit working medium pump sucks/discharges the working medium from/to the first and second chambers respectively via the first and second ports to drive the intensifier.
