Title:
ULTRA-HIGH PRESSURE GENERATOR
Document Type and Number:
Japanese Patent JP2018087550
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To properly manage a temperature of a working medium.SOLUTION: An ultra-high pressure generator has a booster 40 including: a double action-type driving cylinder 44 having a first chamber 41 and a second chamber 42 divided by a piston 43 driven by a working medium F1; and high-pressure cylinders 451, 452 discharging a pressurized fluid F2. The booster further includes: a closed circuit working medium pump 11 for sucking and discharging the working medium F1 to the first chamber 41 and the second chamber 42 and driving the booster 40; a first working medium flow channel 32 and a second working medium flow channel 33; a recovery circuit 34 for recovering the working medium F1 into a tank 31 from the first working medium flow channel 32 and the second working medium flow channel 33; and a low-pressure selection circuit 8 selecting one of the working mediums F1 discharged from the first chamber 41 and the second chamber 42 and conducting the same to the recovery circuit 34 when a pressure of the working medium F1 discharged toward the first chamber 41 and the second chamber 42 is over a predetermined prescribed threshold value.SELECTED DRAWING: Figure 1
