Abstract
Réservoir de gaz sous pression L’invention concerne un réservoir (1) pour gaz sous pression, tel de l’hydrogène, comprenant un joint pâteux (6), une enveloppe d’étanchéité (3), une embase (4) comprenant un évidement (42) accueillant le goulot (32), une cavité externe (44) sensiblement annulaire entre les surfaces convexe (321) du goulot (32) et concave (421) de l’évidement (42), une cavité interne (45) sensiblement annulaire entre les surfaces concave (324) du goulot (32) et convexe (424) de l’évidement (42), le joint pâteux (6) occupant uniformément les espaces externe (44) et interne (45) et assurant ainsi la tenue mécanique et l’étanchéité au gaz entre l’enveloppe (3) et l’embase (4). L’invention concerne également l’enveloppe (3), comprenant un corps (34) et un goulot (32) sur les surfaces duquel au moins deux protubérances (5) s’étendent radialement, angulairement équiréparties.
