Abstract
The invention concerns a plug arrangement for gas-tight closure of a cell vent of a storage battery. To provide a plug arrangement that to the greatest possible extent prevents acid from running out when a storage battery is tipped or turned and at the same time permits sufficient degassing and can also be produced economically, is easy to install and can be adjusted to different battery designs, this invention purposes a plug arrangement for gas-tight closure of a cell vent of a storage battery including a plug that can be used for a seal in the cell vent, an inside of the cell is connected by fluid mechanics to a hollow space made between upper and lower covers of a housing cover for acid deposition through a plug vent in a generating surface of the plug that has a two-way sealed membrane.
