Filling valve for carbonated liquid bottling machines

摘要

Filling apparatus comprising a filling valve which controls the flow of a carbonated liquid from a reservoir to a container. The filling valve includes a tube which extends from the reservoir to the container for equalizing the pressure in the container as the container is filled. When the liquid in the container reaches a predetermined level, venting by the tube automatically ceases. A valve control automatically closes the valve in response to the reduced flow into the container as the pressure builds up within. The initial opening of the valve to permit the flow of liquid into the container and initial opening of the pressure communicating tube is controlled by the two different cams of the actuating mechanism.
