Abstract

Ce diaphragme pour étage de compression de compresseur comporte un ensemble d'au moins un passage (9) traversant s'étendant entre deux faces (6, 7) mutuellement opposées du diaphragme, de manière à créer un flux de gaz entre lesdites faces selon la différence de pression régnant de part et d'autre du diaphragme.
