ABSTRACT:
The device consists of a cleaning assembly (1) and a drive assembly (2). The cleaning assembly is composed exclusively of rigidly mounted and designed cleaning elements (3) forming a ring whose outside diameter increases from front to rear. The drive assembly is provided with flexible sealing disks (5) set vibrating by the action of water pressure and transmitting blows and vibrations to the rigidly connected cleaning assembly (1). Heavy encrustations are thus removed in stages by the cleaning assembly (1) which expands from front to rear.
