Abstract

The device () comprises two outer and inner concentric rings (), one of which is connected to an oil supply from one of the repositories, the other ring being connected to the other repository, the oil flowing between said rings, and bearings between the rings in order to change repositories between the two rings. According to the invention, the device () further comprises a flexible means () forming a shock absorber, provided between a first of said rings and an intermediate ring () that is separated from a second of said rings by said bearings (), said flexible means () defining a deformable sealed chamber () in which oil travels between the two repositories.
