Abstract (en)

[origin: WO9409922A1] The invention pertains to a sanitation device, especially for cleaning pipes (10), with a cleaning part (12) that can be connected to a supply part (14), at least a segment of which is encompassed by a supply tube (26) used to suply an inflatable sealing part (16) with a medium, arranged within the pipe (10) between the supply part and the cleaning part (12). The invention provides that the entire sealing part (16) radially encompasses the supply tube (26), with the sealing part (16) being fastened at its two ends to the supply tube (26) and the supply tube (26) having arranged radially in it apertures that feed into the interior of the sealing part (16). The sanitation device as per the invention provides that even at high pressures, the sealing part has a secure contact with the inner wall of the pipe and cannot be separated in a way that impairs its functioning, particularly not turned up. Moreover, it ensures a low-abrasion sanitizing operation.
