Abstract
A pipe-cleaning device with a cutting head (3) makes it possible to clean clogged pipelines completely, even those clogged with concrete, for example. The cutting head (3) works like a jack hammer as it rotates and is driven only by a pressurized medium, which also rinses the pipeline and carries off the debris. The cleaning device is moved forward automatically by hammer impulses produced by curved disks (12, 22), impulse compensation and the backflow of the pressurized medium in the pipeline, precisely according to its cutting capacity at the time. The cleaning device follows the course of the pipelines and cleans them without damaging them.
