  • Patent number: 10272543
    Abstract: A nozzle ejecting liquid and nozzle device ejecting a liquid upon mixing an abrasive into a liquid jet stream, obtains a converged jet stream. A nozzle includes: a main body; a buffer chamber in the body, whose central axis is an axis line being the liquid jet stream central line; a constrictor part ejecting the liquid, in a buffer chamber plane on a buffer chamber front side and whose central axis is the axis line; a disk plate inside the buffer chamber, facing the plane on the buffer chamber front side and whose central axis is the axis line; a supporting member supporting the disk plate within the buffer chamber; a supply opening in the body supplying the liquid; and an inflow channel along a direction different from the axis line extending direction, opened on a disk plate rear side and the buffer chamber and communicating with the opening.

  • Patent number: 10058978
    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.
