The invention discloses a device (3; 4) for the automatic re-fill of electrolyte into and for the discharge of the fumes from electric accumulators. Said device comprises: a body (10; 100) which can be connected with a lid (1) of an electric accumulator; a tubular element (20) matching inside said body; a tubular stick (30) connected with said tubular element (29) and complete with a floating body (31) co-operating with the liquid (2331) contained in the accumulator, with a flexible membrane (40) and with closing means for the passage of the re-fill liquid. Said flexible membrane (40) increases on said tubular stick (30) the pushing force created by said floating body (31) acting on said closing means (33). |
