Antidrip volumetric rapid filling machine with antifoaming feature and simplified control valve

摘要

This device for rapid and extremely accurate filling of bottles includes means for decreasing the dispensing flow rate during particular phases of each fill. This feature minimizes foaming of dispensed fluids when the filling operation proceeds into the portion of each bottle wherein conditions are conductive to foaming, while maintaining a rapid fill rate for other portions of each bottle. The device also has a novel spool valve for control of flow between supply, metering device and bottle: this valve has a hollow-centered spool, the hollow center providing in one operational configuration a fluid-flow bypass which reduces the number of ports and connections outside the valve barrel.
