ととなる。When the fluid supplied to the high-pressure liquid supply port 1-22a flows into the rectifier pipe 22b, its static pressure is converted into velocity energy, giving it high velocity, and creating a laminar flow while flowing inside the long rectifier pipe 22b. and erupts within 22 e. At this time, if the controlled jet flow from the control port 22c is 0, the jet flow from the rectifier pipe 22b will travel straight without losing much of its velocity energy, pass through the output nozzle 22d, and leave its tip to be cut or damaged. Spouts toward the surface treated object 26,
When cutting or surface treating the object 26 to be cut or surface treated, when there is a control jet from the control port 22c,
Since the jet flow from the rectifier tube 22b is scattered and a considerable portion thereof flows out from the vent 1-22f, the flow rate and velocity energy of the fluid flowing into the output nozzle 22d are significantly reduced.

By doing so, the period can be controlled.
