The desired electrolyte level 13 arises in all cell vessels 3 is the same, with a small amount of electrolyte fluid remaining in the expansion room 2 is to remain as a reserve.

If the electrolyte fluid rises within the cell vessels 3 when the collector is being charged, it then flows through the respective one Overflow pipe 6 back into the expansion space 2, not however, through the respective inlet pipes 5, because namely the resistance formed by the throttle nozzle 11 in the inlet pipes 5 to the flow of electrolyte liquid is greater than the corresponding resistance in the overflow pipes 6. When sinking of the electrolyte level within the cell vessels 3, electrolyte fluid automatically flows from the expansion space 2 through the inlet pipes 5 into the cell vessels 3 until the desired electrolyte level 13 is reached again.

In the figure 2 is a preferred embodiment of the device shown according to the invention; the inlet pipes 5 'manufacturing technology are particularly cleverly designed; the bottom 8 ' of the block cover β 1 'has a pipe socket 17 for each cell container 3', which points downwards, has a lower opening 18 and each dips into a pocket 19 which is attached to a side wall 20 of the block box 4 ' is also formed. The lower opening 18 of the pipe socket 17 has it Distance from the bottom 21 of the pocket 19 and between the pipe socket 17 and the side wall 20, a gap 22 is formed which is open at the top and old outlet opening 10 in the gas space 9 'of the cell vessel 3 'opens. The appropriately dimensioned gap 22 serves as the means 11 ', but the length of the pipe socket 17 can also be used as the means can be used to increase resistance. Tool technology, it is advantageous if the pockets 19 with the upper edge 23 of the box 4 ' are essentially flush · the rest of the structure of this collector corresponds to that of Figure 1; the same goes for the function.
