摘要：This device for maintaining substantially constant the tensile stress applied to aflexible line particularly adapted for equipping the drilling floating installations,comprises the combination of a stationary return member and a return membermoveable with respect to one holding point of the flexible line, said line passingsuccessively over said return members while forming at least a loop portion, themoveable return member being supported at the end of a pivotable arm actuated byjack means fed with pressurized fluid from an oil and air accumulator, the jack rod having,for each position of the moveable return member, a direction different from that of thetravel path of said moveable return member.
