ABSTRACT:
In a centrifugal separator a flexible member for the transport of liquid to or from a centrifuge rotor is arranged to rotate around a rotating rotor in the same direction as the rotor but with only half of its rotational speed. By such rotation the flexible member may be firmly connected with both the rotor and a stationary member without being twisted. According to the invention the flexible member has a high torsional stiffness, good tensile strength and an outside having good wear resistance. The casing comprises interplaited threads which may be metal or plastic, some of which extend helically with a certain pitch around the flexible member and others of which extend helically with an opposite pitch around the member. The interplaiting of the threads is such that the casing per se is axially compressible and expandable under radial expansion and compression, respectively. As mounted, the casing is axially expanded so that through radial compression it is in frictional engagement with the flexible member.
