摘要：
590533 A fluid flow control assembly for regulating fluid flow, and may find particular application in additive dispenser systems. Typically a baffle arrangement (210a, 210b) comprises a plurality of baffle elements (202) within a chamber (208). The arrangement forms an alternating sequence of restrictions and cavities for fluid flowing from an inlet (205) to an outlet (201) and tends to restrict fluid flow in an alternative manner to merely providing a fine diameter aperture. The baffle arrangement comprises a sequence comprising a plurality of baffle elements capable of limited movement, the movement of the baffle elements being limited by the internal walls of the internal chamber. The fluid flow control assembly was developed for applications where foreign particles or air bubbles may block fine diameter apertures, such as low pressure additive dispenser systems where low relatively stable flow rates are important to their operation.
