Abstract

　L'invention concerne un élément de transmission de gaz qui est pourvu d'une feuille de transmission de gaz et d'un corps de retenue. La feuille de transmission de gaz est constituée de manière à être capable d'être fixée à un trou traversant et est capable de transmettre un gaz dans un espace intérieur jusqu'à un espace à l'extérieur d'un corps principal de récipient. Le trou traversant est formé dans le corps principal de récipient ayant l'espace intérieur et permet à l'espace à l'extérieur du corps principal de récipient et à l'espace intérieur d'être en communication. Le corps de retenue comprend un trou de circulation de gaz destiné à la circulation de gaz et maintient la feuille de transmission de gaz dans le trou de circulation de gaz. Le corps de retenue comprend une soupape de sécurité capable d'évacuer le gaz dans l'espace intérieur vers l'espace à l'extérieur du corps principal de récipient lorsque la pression dans l'espace intérieur dépasse une pression prédéterminée.
