Abstract (en)
[origin: CA2810786A1] The invention relates to a device for cleaning, in particular, sewer pipe walls. For this purpose, a nozzle carrier (4) is arranged in a carriage (1) in a rotationally fixed manner. On the rear side of the nozzle carrier (4) having a central hose connection (9), a plurality of nozzles are arranged around the hose connection (9), preferably on two circles (10, 11), said nozzles being oriented at an angle from the main axis (5) of the nozzle carrier (4). Thus not only an axial component directed toward the rear but also a radial component of the jet escaping from the nozzle results. As a result, the jet extends in a spiral on the pipe wall to be cleaned. Thus streak formation, as occurs with a purely axial orientation of the nozzles, is avoided.
