Abstract: A nozzle device produces a more convergent water jet to improve the quality of a cut surface. The nozzle device includes a liquid supply channel for supplying a liquid, an orifice for discharging the liquid supplied from the liquid supply channel to produce a water jet, a straightening unit arranged downstream of the water jet from the orifice and having a through-hole to surround the water jet, a first air supply channel for supplying a gas toward a location upstream of the water jet from the through-hole and toward the orifice, and a second air supply channel arranged downstream of the water jet from the first air supply channel for supplying the gas toward a location inside the through-hole or a location downstream of the water jet from the through-hole.

Abstract: A fluid pressure producing method reduces fluctuations in the pressure of a fluid pressurized using a plunger driven by applying the pressure of a working medium to a double-acting piston. The method includes switching a moving direction of the piston when detecting the piston reaching a movement end, operating the working medium pump to discharge the working medium at a maximum flow rate while the load is less than the load limit after the moving direction of the piston is switched, and detecting a pressure of the fluid and feeding back the detected pressure of the fluid and performing feedback control of the pressure of the fluid to eliminate a difference between the pressure of the fluid and a target pressure of the fluid.

Abstract: The temperature of a working medium is managed appropriately. A pressure intensifier includes a double-acting drive cylinder having first and second compartments separated by a piston driven by a working medium, high-pressure cylinders that discharge the fluid, a closed-circuit working medium pump that drives the pressure intensifier by sucking and discharging the working medium from and to the first and second compartments, first and second working medium channels, a collector that collects the working medium from the first and second working medium channels into a tank, and a low-pressure selector that selects, when the pressure of the working medium discharged toward the first or second compartment exceeds a predetermined threshold, the working medium discharged from the first or second compartment, and directs the selected working medium to the collector.
