AUTOMATIC DOSING AND SPRAYING VALVE ASSEMBLY

WIPO Patent Application WO/2014/016543

A3

A non-electrically powered automatic dosing and spraying valve assembly for a container of pressurised fluid with an outlet valve is described, wherein the valve assembly comprises a housing containing at least two chambers wherein one of those chambers is a main chamber open at one end to the contents of the container and closed at one end by a movable plunger, and another of those chambers is a dose chamber closed at one end by the movable plunger and closed at the other end by a prodder seal formed between a movable prodder and a fluid outlet opening; wherein the movable plunger is biased against movement toward the dose chamber by a main spring means and a prodder spring means, the main spring means being mounted in or adjacent to the dose chamber and the prodder spring means being connected to both the movable plunger and movable prodder, the assembly further comprises a fluid leak path between the main chamber and the dose chamber; and wherein the assembly is arranged such that, in use, one movable component of the assembly is configured to move relative to another component of the assembly to temporarily expose the dose chamber to the full fluid pressure of the main chamber.
