Abstract

Pivoting arm device on a support, consisting of: - said support, - said arm pivotally mounted on this support around a substantially horizontal axis, - and, an element for adjusting the pivoting of this arm connected between the latter and the support and which in particular makes it possible to maintain said arm in a certain position in relation to said support, characterized in that a fluid-powered mechanism, of the volumetric type, different from the pivot adjustment member, is also connected between the support and the arm and includes a chamber, called discharge, connected by a main duct with a low fluid accumulator pressure and filled with a given fluid, which, when the arm pivots so that its free end lowers, is ejected out of said discharge chamber in said fluid accumulator under pressure.
