A system for applying a working pressure on a content of a pressure package (A) with the aid of a propellant, the system being provided with: a pressure package (A) and a gas supply device (B) comprising a pressure controller ( 2 ) and a high-pressure chamber for storage of the propellant, the gas supply device (B) being provided with a feed-through connecting the high-pressure chamber and the pressure controller to enable propellant to flow from the high-pressure chamber ( 3 ) to the pressure controller, the pressure controller being further arranged to control the working pressure on the content of the package with the aid of the propellant on the basis of a predetermined reference pressure, the gas supply device being furthermore provided with a movable member ( 5 ) which can be brought at least into a control position and into a neutral position, while the movable member in the control position clears the feed-through to enable control of the working pressure, and the movable member in the neutral position blocks the feed-through.
