Abstract
Device for elimination of vibrations of a valve for decompression of an enclosure containing a fluid under pressure, comprising a lever articulated on the valve body in two parts. The first part is integrally fixed to a spindle mounted to rotate in the valve body. This part comprises a rocker arm and its end opposite the rocker arm is connected to the valve stem. The second part is connected to the moveable armature of an electromagnet and comprises a bearing surface for the tappet. The two parts of the lever are connected through the intermediary of a friction coupling. Movements of the valve beyond the position of locking by the electromagnet are damped by the friction coupling. The invention is applicable in particular to a decompression valve in a pressurized water nuclear reactor.
