Abstract
A filler cap for accumulator batteries with liquid electrolyte is used for automatic filling of the battery cells. The filler cap has a case (1). The case (1) has an opening (3) the a water pipe (4). A valve seat (5) connected by a rod (7) to a float (6) is used to close the opening (3). When the water level in a cell has dropped, the float (6) opens the valve (5) and water flows through holes (11, 14) into the cell. Other holes (16, 17, 18) allows gas to escape.
