ABSTRACT:
A pressure-actuated valve is adapted to the discharge port of a positive displacement machine for filling, sequentially, passing open containers with a liquid product. In response to the sequential pulses of liquid produced at the discharge port, the pressure-actuated valve opens and closes to deliver a predetermined amount of liquid to a waiting container. Even with low viscosity fluids, operation of the valve remains effective, permitting release of fluid during the delivery period yet preventing contaminating drips of fluid from the nozzle during non-delivery periods. Owing to the special valve design, delivery of accurate amounts of liquid and elimination of nozzle drip between container filling cycles are ensured, regardless of slowdown or interruption of machine operation. Contamination of the filling station resulting from product splash is also eliminated despite high speed operation of the machine.
