ABSTRACT:
A device for maintaining the electrolyte level in the accumulator of an electric battery includes a pneumatic chamber, with levelling members in it, connected to the accumulator, and a reservoir for supplying liquid to the pneumatic chamber. The levelling members assure a constant level of liquid in the pneumatic chamber. When the electrolyte level in the accumulator drops below a preset limit, the resulting reduction in pressure in the pneumatic chamber permits reservoir liquid to enter the accumulator, until the level of electrolyte in the accumulator rises enough to raise the pressure in the pneumatic chamber to stop flow of liquid into the accumulator.
