Abstract
An ultrahigh pressure generator is disclosed. The ultrahigh pressure generator has a pressure intensifier that discharges a fluid at ultrahigh pressure. The pressure intensifier uses a working medium and includes a double acting drive cylinder with a first compartment and a second compartment that are separated by a piston. A closed-circuit working medium pump drives the pressure intensifier by sucking and discharging the working medium from and to the first and second compartments. A collector collects the working medium from the first and second working medium channels into a tank. A low-pressure selector selects whether the working medium is discharged from the first or second compartment when the pressure of the working medium discharged toward the first or second compartment exceeds a predetermined threshold, and directs the selected working medium to the collector. The pressure generator manages the temperature of the working fluid appropriately.
