Abstract:
1. A fluid dispensing nozzle for dispensing and cutting off a stream of liquid into a container, the fluid dispensing nozzle comprising: a housing having a fluid flow path therethrough, the housing having an upper portion defining an inlet and a lower portion defining an outlet; a discharge check valve disposed within the housing, between the inlet and the outlet, the discharge check valve having an open position allowing a stream of liquid flow from the inlet to the outlet, an intermediate position that stops the liquid flow through the discharge check valve, and a closed position, wherein the discharge check valve is capable of creating a vacuum pressure at the outlet end during closing between the intermediate position and the closed position; and at least one perforated plate being supported by the housing and being positionable and confinable within the fluid flow path at the outlet, the at least one perforated plate having a plurality of apertures therethrough wherein there are at least two differently sized apertures including at least one larger size aperture and at least one smaller size aperture, wherein the at least one larger size aperture is positioned radially inboard of the at least one smaller size aperture, wherein the created vacuum pressure applied at the at least one larger size aperture increases the rate of decay of the liquid stream for dispensing into the container.
