  • An embodiment of the gas pressure accumulator according to the invention provides before that the metal bellows when supplying and removing the fluid Performs lifting movement by means of which the valve arrangement is actuated becomes. As a result, the closing of the fluid space is immediate coupled with the movement of the metal bellows, whereby a self-contained security system is formed.
