Apparatus for filling successive containers with a liquid, such as a carbonated beverage, has a rotary vessel with a bottom wall which carries an annulus of tubular extensions each of which is surrounded by a metering chamber. Each extension and the associated metering chamber supports a filling unit with a twin-seat valve having a single valving element which is movable between an upper position to seal an outlet at the lower end of the extension from an adjacent inlet of the metering chamber while permitting the outlet of the metering chamber to discharge a metered quantity of liquid into a container below the filling unit, and a lower position in which the single valving element seals the outlet of the metering chamber but permits the extension to admit liquid into the metering chamber. The mechanism for moving the valving element between its upper and lower positions independently of the speed of the vessel employs a spring which biases the valving element to its upper position when the underside of the valving element is acted upon by atmospheric pressure, and a mechanical flip-flop which can lower the valving element against the resistance of the spring. Flow restrictors are provided to limit leakage of the liquid during movement of the valving element between its positions.

The centering nozzles of continuously orbiting material-supplying valves in a filling machine wherein cans, bottles or other types of containers are moved into register with and advance with the valves in the course of the filling operation are biased toward the material-receiving portions of registering containers by mechanical springs or by pneumatic cylinder and piston units in order to ensure that the nozzles can yield when necessary so as to preserve the integrity of the valves and/or of the containers. The springs and/or the cylinder and piston units are interposed between the nozzles and the assemblies which serve to raise and lower the nozzles relative to the containers below them. The nozzles also serve as differential pistons to bias their sealing elements against the adjacent containers during actual admission of a flowable material.
