Abstract

Soupape de décharge de surpression. L'ailette 47 constitue une extension périphérique de la surface centrale de poussée 34 qui accélère le mouvement d'ouverture dès que l'obturateur 27 commence à s'écarter de son siège 14. Applications : soupapes de décharge de surpression.Pressure relief valve. The fin 47 constitutes a peripheral extension of the central thrust surface 34 which accelerates the opening movement as soon as the shutter 27 begins to move away from its seat 14. Applications: overpressure relief valves.
