Abstract (en)
[origin: US2004025906A1] The device comprises a spray system (72, 74, 78, 80, 82, 84, 85, 86) for spraying a fluid (76) against the inside periphery of the tube (1) to be cleaned, and two analogous brushing assemblies (10, 20), each of which comprises brushing means (12, 22) and a propelling element which co-operates with the inside periphery of the tube (1). The device further comprises means (50, 30, 40) for moving axially the brushing assemblies towards each other and away from each other in alternation, which means comprise a chamber (58) connected to a feed for feeding in fluid (51) under pressure. Said spray system (72, 74, 78, 80, 82, 84, 85, 86) includes a reservoir (72) put under pressure by being connected to said chamber (58).
