Beschreibung
Zusammenfassung:	The present invention relates to liquid dispensing devices having discharge nozzles. The discharge nozzle has a flow control device. The flow control device includes a check valve and an outlet. The check valve is capable of creating a vacuum pressure cycle during closing. The outlet is formed from at least one perforated plate. The perforated plate has a plurality of apertures therethrough. The plurality of apertures include at least two differently sized sets of apertures. The at least two differently sized sets of apertures include a larger size set of apertures and a smaller size set of apertures. The larger size set of apertures are centrally located within the perforated plate. The present invention helps to concentrate the greatest vacuum pressure on a decaying portion of a stream of liquid right in the center of the outlet of the discharge nozzle.
