  • Patent number: 5016687
    Abstract: In a liquid filling machine wherein a liquid is fed in a specified quantity at a time from a metering cylinder to a filling nozzle by the operation of a piston housed in the cylinder, a device for preventing the liquid from dripping from the filling nozzle comprises a check valve disposed in the nozzle and movable upward or downward by a change in the internal pressure of the metering cylinder produced by the operation of the piston. The upward movement of the valve produces a negative pressure within the nozzle to prevent the liquid from dripping from the nozzle. The negative pressure is variable in accordance with the properties of the liquid by adjusting the stroke length of upward or downward movement of the check valve.

  • Patent number: 4410108
    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.
