The device serves to automatically fill battery cells (10) with water with a filler plug (14) that can be placed in the cell. The latter has two connection pieces (24) for the water supply as well as a valve operated by a float (96), the valve body (62) of which is connected in articulated fashion to the float (96) arranged centrally in the plug housing (16) via a pivotally mounted amplifying lever (74). Between the valve with the suspended body (62) and the connection piece (26) there is a substantially vertical overflow wall (60), the free upper edge of which is higher than the horizontal upper edge of the bore of the connection pieces (26), from which a U-shaped feed duct (94) leads to the overflow wall (60).

L'invention concerne un dispositif permettant de remplir automatiquement d'eau des éléments de batterie (10), à l'aide d'un bouchon de remplissage (14) insérable dans l'élément concerné. Ce bouchon de remplissage (14) comprend deux tubulures de raccordement (24) pour l'alimentation en eau, ainsi qu'une vanne actionnée par un flotteur (96), le corps de la vanne (62) étant relié de manière articulée au flotteur (96) disposé de manière centrée dans le boîtier du bouchon (16), par l'intermédiaire d'un levier d'amplification (74). Entre la vanne à corps (62) suspendu et les tubulures de raccordement (26), il est prévu une paroi de trop-plein (60) sensiblement verticale dont l'arête supérieure libre se situe plus haut que l'arête supérieure horizontale de passage des tubulures de raccordement (26) d'où part un canal d'amenée (94) en U qui mène à la paroi de trop-plein (60).
