Filling valves for counterpressure filling of containers with carbonated liquids. The filling valves comprise valve bodies for conducting the carbonated liquids to the container from an external reservoir, the valve body having an end from which the carbonated liquid is dispensed to the container. The valves further comprise counterpressure valves movably mounted in the valve body for controlling the flow of counterpressure gas to the containers. Vent tubes mounted in the valve bodies through the dispensing end of the valve bodies, the vent tubes being slidable with respect to the valve bodies from a retracted position to an extended position in the containers in response to the counterpressure gas are provided. Pressure relief passages interfaced through the valve bodies for venting gas from the valves after the liquid has filled the containers whereby movement of the vent tubes from the extended position to the retracted position is substantially unimpeded are further provided. Housings movably mounted with respect to the valve bodies for securing the containers to the valves during filling and actuating cams coupled thereto for moving the housings relative to the valve bodies onto the containers are further provided in accordance with the invention.

A filling valve for counterpressure filling a container from an external reservoir with carbonated liquids of the type in which the filling valve is vertically moveable with respect to a container at a stationary vertical position, comprising: valve body means for conducting the carbonated liquid to the container from said external reservoir, the valve body means having an end from which the carbonated liquid is dispensed to the container; cam operated counterpressure valve means movably mounted in the valve body means for controlling the flow of counterpressure gas from the reservoir to the container; tube means coupled to said counterpressure valve means for receiving counterpressure gas; vent tube means in fluid communication with said tube means and slidably mounted in the valve body means through the dispensing end of the valve body means for dispensing the counterpressure gas to the container, the vent tube means being slidable with respect to the valve body means from a retracted position within the valve body and substantially outside said container to an extended position protruding beyond the valve body and inside the container in response to the counterpressure gas, whereby the counterpressure gas is dispensed from one or more ports on the vent tube while disposed within the container and beyond the valve body; pressure relief means interfaced through the valve body means for venting gas from the valve after the liquid has filled the container whereby movement of the vent tube means from the extended position to the retracted position is substantially impeded; housing means movably mounted with respect to the valve body means from an upward position to a downward filling position for securing the container to the valve during filling; and actuating means coupled to the housing means for moving the housing means relative to the valve body means to the downward filling position and onto the container.
