| 摘要 |
The invention concerns an articulated arm for transferring fluid products comprising two tubular sections (7, 8+2) mutually linked by a pivoted connection (3) with horizontal axis, and a balancing device (4, 10) linked with each of the tubular sections to compensate torque variations about the pivoted connection axis while the two sections are rotating relatively. The invention is characterised in that the balancing device comprises a U-shaped spring (10) with two branches (11, 12) whereof the ends (11A, 12A) are each connected to a respective section.
