Abstract: A pressure package system for providing a working pressure on a fluid included in a pressure package, the system being provided with a pressure package in which a product chamber is included for holding the fluid and in which a working pressure chamber is included for keeping a propellant at the working pressure, the system being further provided with a pressure controller and a high-pressure chamber connected with the pressure controller for keeping the propellant in supply at a relatively high pressure, the pressure package system being further provided with a wall which is of elastic and/or flexible design, a first side of the wall bounding the working pressure chamber at least partly and a second side of the wall, facing away from the working pressure chamber, bounding the product chamber at least partly.

Abstract: 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 bloc
