Abstract
PURPOSE: To simplify the construction by interposing a shut-off valve opened or closed by a pilot pressure respectively to a high pressure water capillary tube connected to a jetting nozzle and jetting the high pressure water by operating the shut-off valve only in the range of a certain rotating angle. CONSTITUTION: An oil chamber 15 connected to a pilot path 17 is arranged in a slide hole of a piston 13 of a pilot check valve 7, and other end of the path 17 is connected to a rotary seal 18 provided between a rotary shaft 3 and the main body 19 of a drive machine. Also, oil pressure is applied through a jetting direction transfer valve to four pilot pressure supply port 20. And when the natural ground is excavated in right direction for example, the jetting direction transfer valve is switched, and the oil pressure is supplied to the port 20 at the right side only when the nozzle 4 comes to the right half rotary position, an inlet port 8 and an outlet port 9 are communicated, and the high pressure water is supplied from the conduit 5 to the nozzle 4.
