Apparatus for the distribution of fluid materials, notably liquids such as oils and essential oils, perfumes, and the like, which are typically at least somewhat corrosive vis-a-vis injection heads for the dispensing thereof, includes a distribution nozzle, the geometry and mode of operation of which prevent the backup of distributed material into the dispensing nozzle/system during shutdown, and advantageously a control for the automatic regulation of the starting and stopping of the dispensing function.
