DEVICE FOR CONTROLLING THE PRESSURE IN AN AEROSOL DISPENSINGCONTAINER

摘要

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 hi gh- pressure chamber (3) to the pressure controller, the pressure controller bei ng further arranged to control the working pressure on the content of the packa ge 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 th e feed-through to enable control of the working pressure, and the movable memb er in the neutral position blocks the feed-through.
