<p>The invention concerns a lid (1) for an electric accumulator (A) containing an electrolyte. The lid (1) comprises: a shaped closing element (2) suited to be coupled with the container (16) of the accumulator (A) and in which it is possible to identify one or more holes (3) spaced from one another, each one of which is suited to accommodate a cap for the introduction of the electrolyte in the container; a discharge hole (5a, 5b) obtained in the shaped closing element (2) in order to allow the gas produced in the container (16) to flow out. The lid (1) also comprises:
- one or more first labyrinth portions (6a, 6b, 6c, 6d, 6e, 6f) obtained in the internal surface (7) of the shaped closing element (2), each one of which is developed around one of the holes (3) and is provided with at least one through hole (8) in communication with at least one discharge hole (5a, 5b) or with a first labyrinth portion adjacent to it;
- one or more second labyrinth portions (9a, 9b, 9c, 9d, 9e, 9f) obtained in one or more shaped bodies (9) that are external to the shaped closing element (2). The first and the second labyrinth portions (6a, 6b, 6c, 6d, 6e, 6f; 9a, 9b, 9c, 9d, 9e, 9f) have matching profiles suited to be tightly coupled with each other so that, once the coupling operation has been completed, the first and the second labyrinth portions can form one or more labyrinths.</p> |
