发明名称	Safety valve having a hydraulic brake.
摘要	<p>L'équipage mobile de la soupape est sensible à la pression régnant dans une enceintepour ouvrir la soupape lorsque cette pression dépasse une valeur limite. Un frein hydraulique (44) est inséré dans l'équipage mobile entre le clapet (30) et le ressort de rappel (34). Il comprend un piston (50) divisant un cylindre (48) en deux chambres à volume variable (54, 56) qui communiquent entre elles par au moins un passage calibré (58). Application notamment aux soupapes de sûreté équipant les circuits d'eau des centrales nucléaires.</p>
