The invention concerns a plug arrangement for gas-tight closure of a cell vent (2) 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 proposes a plug arrangement for gas-tight closure of a cell vent (2) of a storage battery composed of a plug (4) that can be used to seal the cell vent (2), whereby the inside (3) of the cells is connected by fluid mechanics to a hollow space (5) between the upper and lower covers (6, 7) of the housing cover (17) for acid deposition through a vent (10) in the generating surface (11) of the plug (4) that has a two-way sealed membrane (12).
A plug arrangement for closing a cell vent (2) of a storage battery so it is gas-tight, composed of a plug (4) that can be used for a seal in the cell vent (2), whereby the inside (3) of the cell is connected by fluid mechanics to a hollow space (5) made between the upper and lower covers (6, 7) of the housing cover (17) for acid deposition through a vent (10) in the generating surface (11) of the plug (4) that has a two-way sealed membrane (12).
The plug arrangement in one of the preceding claims, characterized by the fact that the vent (10) made in the generating surface (11) of the plug (4) is arranged opposite the access (15) to the hollow space on a plug (4) used in the cell vent (2).
The plug arrangement in one of the preceding claims, characterized by the fact that the plug (4) has a rotating seal (8) on top, which in a plug (4) used in the cell vent (2) in the area of the upper cover (6) bears down on the wall surrounding the cell vent (2) to seal it and seals the hollow space (5) opposite the air surrounding the storage battery.
The plug arrangement in one of the preceding claims, characterized by the fact that the plug (4) has a rotating seal (9) on the foot, which bears down on the wall surrounding the cell vent (2) to seal it in the area of the lower cover (7) on a plug (4) used in the cell vent (2) and seals the hollow space (5) opposite the inside (3) of the cells.
The plug arrangement in one of the preceding claims, characterized by the fact that both the round seal (8) and the laminar seal (9) are designed in one piece on the plug (4).
