Abstract

A filling valve arrangement for a counter-pressure container filling apparatus in which the filling valve arrangement is mounted in a bottom outlet opening in the usual bowl which holds the liquid under gas pressure, and an extension on the filling valve supports a filling head to receive the neck of a container in operative position so that a gas vent control carried by the vent tube is located in the container to admit gas into the container and to vent gas from the container as liquid replaces the gas in a rapid exchange of liquid for the gas up to the desired liquid level. The filling valve arrangement provides a space adjacent the liquid admitting valve for retaining a body of liquid in position for immediate admission in a very short period of time, and the gas vent control provides a device that can be snap-fitted onto many of prior types of vent tubes, but which is especially adapted to permit a range of weight adjustments to improve the positive response to the cut-off of the liquid fill as the gas is expelled from the container.
