Abstract: The invention relates to an actuator for a dispenser device for spraying contents of a receptacle that is pressurized or of a receptacle that has a pump, the actuator comprising a channel connectable to a receptacle outlet on one side of the actuator for receiving the pressurized contents of the receptacle, said channel having an orifice for spraying the contents on another side of the actuator, wherein an inlet connects the channel with a volume chamber, wherein the orifice has a valve for opening and closing the orifice, the valve biased by biasing means in the closed position, wherein the inlet has inlet reduction means for reducing the size of the inlet to the volume chamber. The invention is characterized in that the inlet reduction means comprises a flexible element.

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 (2) in which a product chamber (4) 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 (5) and a high-pressure chamber (6) 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 (7) which is designed to be movable relative to the pressure controller, a first side (8) of the wall bounding the working pressure chamber at least partly and a second side (9) 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
