  • Apparatus for producing ultrahigh pressure water jet
    Patent number: 4600149
    Abstract: An ultrahigh pressure water apparatus converts feed water of normal pressure into ultrahigh pressure water by means of an ultrahigh pressure pump and projects the ultrahigh pressure water through a nozzle gun in the form of jets of ultrahigh pressure water. The nozzle gun has an eccentric shaft tube rotatably disposed inside a nozzle cover, a high pressure hose rotatably inserted into the eccentric shaft tube, and nozzles fastened to the leading end of the high pressure hose. Owing to the rotation of the eccentric shaft tube, the jets of ultrahigh pressure water projected through the nozzle are sympathetically rotated.
