Abstract
Disclosed is a an improved dispensing system which allows nitrogenized liquids to be dispensed from a relatively low pressure dispensing system (i.e., one operating in a relatively low pressure range). To accomplish this, the improved dispensing system includes holes having very small cross-sectional areas. The improved dispensing system may be formed so as to facilitate the manufacturability of the holes required for the proper dispensing of nitrogenized liquids. For this purpose, the improved dispensing system may include a dispensing valve body and an insert member having a plurality of grooves therein. When the insert member is inserted within the valve body, the insert member grooves, along with a portion or portions of the valve body, together form the plurality of holes required for the proper dispensing of nitrogenized liquids.
