Abstract:
1. A housing for a gas-tight rechargeable battery, comprising: a proportional valve arranged at an opening in a wall of the housing, the proportional valve movable between a maximum open position and a normally closed position, the proportional valve having a valve body influenced by force in the direction of the closed position and towards the interior of the housing, the proportional valve being at least in part embodied from metal and configured to be connected to the cathode of the rechargeable battery in an electrically conductive manner; and a contact element being at least in part embodied from metal and configured to be connected to the anode of the rechargeable battery in an electrically conductive manner, wherein the proportional valve is configured such that in the maximum open position it allows the gas to escape from the housing if the pressure that is prevailing in the housing exceeds a construction-dependent pressure limit value until the pressure that is prevailing in the housing no longer exceeds the construction-dependent pressure limit value, and wherein the contact element is arranged on the outside of the housing in such a manner that the valve body comes into physical contact with the contact element after the proportional valve has achieved a defined open position.
