Patent ID: 8257458

Claim:
A cyclonic fluid separator with a tubular housing ( 10 ) in which the fluid is accelerated and swirl imparting means ( 2 ) for inducing the fluid to swirl through an annular space between the housing and a central body ( 1 ) mounted within the housing ( 10 ), characterized in that the central body ( 1 ) is provided with resonance abatement means, wherein the resonance abatement means comprise: tensioning means ( 20 , 22 ) which apply a tension load to an elongate tail section ( 8 ) of the central body (I) such that the natural frequency of the central body ( 1 ) is increased, wherein the tensioning means ( 20 , 22 ) comprise a clamp construction to hold the downstream end of the central body ( 1 ) in position, the clamp construction comprising a conical tube ( 20 ) and a clamp housing ( 22 ), wherein the conical tube ( 20 ) is tightly squeezed between the outer surface of the tail section ( 8 ) of the central body ( 1 ) and the inner surface of the clamp housing ( 22 ).
