In a gas-tight alkaline accumulator with a casing which at least partially comprises plastic material and in which are arranged electrodes which are surrounded by an electrolyte and which are respectively separated from each other by a separator, wherein the electrodes are connected to pole contacts for electric current to be fed to and away therefrom, in order to increase the operating reliability of the accumulator and to avoid further disadvantages there is provided a valve having an opening which passes through the casing of the accumulator, and a deformable element which, in the event of an increased pressure occurring within the casing, provides for liberation of the opening and, after a drop in the increased pressure, closing of the opening.
L'invention concerne un accumulateur (1) alcalin étanche aux gaz qui comporte un boîtier (2) réalisé au moins en partie en plastique, dans lequel se trouvent des électrodes (6) entourées d'un électrolyte et séparées mutuellement par un séparateur (4). Les électrodes sont reliées aux contacts polaires (8) pour amener et évacuer le courant électrique. Afin d'améliorer la sécurité de fonctionnement de cet accumulateur et d'éviter d'autres inconvénients, il est prévu une soupape (9) pourvue d'une ouverture (10) qui traverse le boîtier de l'accumulateur et d'un élément (11) pouvant être déformé qui dégage l'ouverture en cas de surpression à l'intérieur du boîtier et l'obture lorsque la surpression disparaît.
