NOZZLE

摘要

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.

主权项

1. A nozzle adapted to eject liquid, comprising:
a main body; a buffer chamber provided in the main body, whose central axis is an axis line serving as a center line of a jet stream of the liquid; a constrictor part adapted to eject the liquid, provided in a plane of the buffer chamber on one side according to a direction of the axis line and whose central axis is the axis line; a disk plate provided inside the buffer chamber, the disk plate facing the plane of the buffer chamber on the one side and whose central axis is the axis line; a supporting member adapted to support the disk plate within the buffer chamber; a supply opening provided in the main body, adapted to supply the liquid; and an inflow channel provided along a direction different from an extending direction of the axis line, the inflow channel opened on the other side of the disk plate and the buffer chamber opposite to the one side and communicating with the supply opening.
