<p><P>PROBLEM TO BE SOLVED: To attain whole miniaturization, improvement of maintainability and rise of washing efficiency under low water pressure in a washer for the inside of a pipe in which a beating and picking member is attached at an eccentric position of an injection nozzle rotatably attached to a top end of a flexible hose and an inner surface of the pipe is washed by spraying the injection water and beating a beating brush while rotating and advancing the injection nozzle by injecting water from the injection nozzle. <P>SOLUTION: The washer has a high pressure water injection nozzle constituted of respective members comprising a supporting body 1 composed of a concentric cylinder which has a plug section 12 for being inserted in a flexible hose at a top end thereof and in which a high pressure water path 11 is formed, an eccentric rotary body 2 composed of a cylindrical body which is attached to an outer peripheral surface of an top end side than the plug section 12 of the supporting body 1 via a seat bearing 21 and which eccentrically rotates, a scraping balancing material 3 which is fixed to an outer surface of the eccentric rotary body 2 and a head cap 4 which is attachably / detachably attached to a top part of the eccentric rotary body 2 at a top end side position than the supporting body 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
