Abstract

L'invention concerne un dispositif d'égalisation de pression (1, 201, 301, 401 ) pour un boitier de batterie. Le dispositif comprend une cage (2, 202, 302, 402) décrivant un passage de fluide (23, 223, 323, 423), un couvercle (4, 204, 304, 404) monte sur la cage et une membrane (34, 234, 334, 434) couvrant le passage de fluide pour égaliser la pression a I'intérieur du boitier avec la pression ambiante a I'extérieur du boitier. Le couvercle est mobile, en utilisation, entre une configuration ouverte, dans laquelle l'air peut s'échapper, et une configuration fermée, dans laquelle le boitier est scellé.
