Patent ID: 8225848

Claim:
A device for reducing fouling in a tube ( 1 ) through which a fluid passes, said device comprising; a mobile rotary element ( 3 ); and a fixed bearing-forming element ( 2 ) that is solidly connected to the upstream end of the tube ( 1 ), wherein: the mobile rotary element ( 3 ) is connected to the fixed bearing-forming element ( 2 ) and comprises an upstream trunnion-forming part ( 4 ) and a downstream turbulence-generating part ( 5 ), shaped so as to be rotated by the fluid flowing in the tube ( 1 ), the upstream trunnion-forming part ( 4 ) and the downstream turbulence-generating part ( 5 ) are connected to one another by an elongate flexible connector ( 6 ) deformable along its whole length, fitted to permit damping of the dislodging force exerted by the mobile rotary element on the fixed bearing-forming element, and wherein the downstream turbulence-generating part forms a separate and distinct element from the elongate flexible connector, with one end of the elongate flexible connector being connected to the downstream turbulence generating part.
