Battery filling and venting structure
A battery with at least one filler connection for electrolyte liquid is described in which the battery interior space is adapted to be connected with the atmosphere by way of at least one venting connection. The opening of the venting connection which terminates in the battery interior space is located geodetically approximately at the height of the intended liquid level. A fill-in chamber is interconnected between the opening of the filler connection which terminates in the atmosphere and the battery interior space. The fill-in chamber is connected with the battery interior space by means of a chamber connection whose opening terminating in the battery interior space is located geodetically above the intended liquid level. The free cross section of the chamber connection is dimensioned so small that a liquid seal closing off the chamber connection in a gas-tight manner will form under the influence of the excess pressure which will establish itself in the battery interior space above the liquid level during the fill-in operation once the liquid has entered into the opening of the venting connection which terminates in the battery interior space.
