Abstract

Accumulator with common filler and expansion chamber for the electrolyte liquid of the individual cells. The object is to facilitate the addition of the correct amount of electrolyte, the check and replenishment of distilled water and to prevent the leakage of electrolyte when the accumulator is tipped over. The feed of the liquid from the expansion chamber is via a communicating tube whose column of liquid is higher than the liquid column formed in the overflow tube. This produces a resistance to the pressure build up of gas in the cell preventing a link between the individual cells. The inlet end of the tube is in the expansion chamber and the outlet end in the allotted cell chamber.

Description

Electric collector with common filling and expansion space for the electrolyte fluid of the individual cells The invention relates to a maintenance-free, tilt-proof electrical collector with electrolyte fluid is filled.

Electric collectors with a common filling space, as well as with recombination catalysts for hydrogen and oxygen to water, are known as such and are not an issue this registration.

The disadvantage of the known collector is that the cell vessels different levels of electrolyte liquid speed, as a result of gas formation during overcharging and discharging, filling up, even if the collector is shaken, what cannot be avoided in vehicles, the individual cell vessels fill up slowly or less with distilled water or electrolyte fluid, which increases the functional and the life of the collector is also impaired when the collector is tilted a galvanic connection is established via the inlet openings of the cell vessels, which leads to a greater self-discharge of the collector.

The invention is based on the object / also with multicellular ones Electrolyte liquid to be filled electrical collectors: a) the filling of the electrolyte liquid to facilitate b) the checking and refilling of distilled water is not required to make c) the leakage of the electrolyte liquid also when tilting the collector largely to prevent.

This object is achieved according to the invention in that the inlet of the electrolyte fluid from the expansion space into the cell vessel through a communicating Tube or such a channel, the liquid column of which is larger than the column of liquid that can form in the overflow pipe and thus the in the gas pressure developing in the cell has a lower resistance than that in the overflow pipe, opposed, without a galvanic connection between the individual cells - even when tilting the collector - to manufacture.

It is particularly advantageous for the valve action in the present case Invention that the outlet end of the communicating tube opens into a chamber, whose outlet opening reads deeper than the end of the overflow pipe, which the Determines the height of the liquid level in the cell vessel.

An additional advantage of this invention is that the feed and overflow for the electrolyte liquid no valves, floats, porbse inserts or the like

needed.

The subject matter of the invention is shown in an exemplary embodiment and explained in more detail below; It shows: FIG. 1 the longitudinal section of a cell vessel with a common expansion space for the electrolyte fluid of a multicellular one Collector in side view; Fig. 2- shows a cross section of a cell vessel in the area a communicating pipe.

The cell vessel 3 shown in section in FIGS. 1 and 2 has a cover 1 fixed to the collector by a known method, the one for several cells forms common expansion space 2 and by a cover plate 11 in which a closable opening 9 is located, is covered.

The expansion space 2 is in the area of each cell by a communicating Tubes 4 are connected to the cell vessel 3 via the chamber 5. In addition, is the cell vessel 3 through an overflow pipe 8, which with its lower end 8a also the height of the Electrolyte level 7 in the cell vessel 3 determined, connected.

Is in the expansion space 2 through the opening 9 electrolyte liquid filled, the liquid flows through the communicating tubes 4 into the chamber 5, and without filling it through the outlet opening 5a into the cell vessel 3.

The rising electrolyte level 7 in the cellular structure 3 closes again Reaching the overflow pipe 8 its lower end 8a, wherein in the chamber 5 a Air cushion remains, which can no longer be narrowly calibrated and a further inflow from Prevents electrolyte fluid in a known manner. The electrolyte level adjusts itself to the same level in all cell vessels, with a small amount of liquid remaining can remain in the expansion space as a reserve.

At the latest when the collector is overcharged, the electrolyte becomes liquid partially displaced again by gas bubbles forming on the plates, increases prevented by the larger column of liquid in the communicating tube 4 in the overflow pipe 8 and flows back into the expansion space, after which the sth further developing gas pressure escapes through the pipe into the expansion space and here is recombined to water by a catalyst.

If the gas formation in the cell vessels decreases, it flows automatically again electrolyte fluid from the expansion chamber, 2 into the cell vessels.
