摘要

The high pressure flushing device has a HP water feed hose and a nozzle head (5) fitted to it and provided with rearwards pointing water outlet nozzles. A toroidal pressure chamber (2) has a centrally located water flow dividing cone (6) from which are provided a number of rearwards pointing jet nozzles with different angles. Holes (3a-3d) are bored from the vertical axis through which water under high pressure is collected for circulation. Water outlet jets (8) are bored on a ring and ensure direction cleaning of the pipe wall.
