Abstract
A dispensing device for a powder filling machine comprises a duct with at least one dispensing outlet from which a powder material is directed into a container positioned beneath. The outlet incorporates an iris diaphragm with a plurality of occluding elements capable of movement between an operating condition in which the outlet is closed, disallowing passage of the powder material, and a non-operating condition in which the outlet is open, with the occluding elements compassing a flow section aligned concentrically with the duct and allowing the passage of the powder material.
