Cette invention intéresse les contructeurs de soupapes de sécurité et autres organes hydrauliques de sécurité.
The damper consists, in combination, a piston (18) mechanically connected to the valve rod, sliding in a closed composite chamber (20) formed of two chambers arranged on either side of the piston, a large chamber (23) upper part and a compression chamber (24) in the lower part filled with the same hydraulic pressure medium, the piston having, integral to its free face in the large chamber a deformable hollow body filled with a fluid contracted gas at rest by the pressure in the chambers, said chambers communicating with a hydraulic connection amortization thin-wall nozzle (26), the chamber containing the hollow body comprises a visual communication to see its upper side. The invention is particularly contructors safety valves and other hydraulic security organs.
