Abstract
A filling element includes a filling-element housing and a liquid-carrying duct formed therein that ends in an opening for discharging liquid product into a container. A liquid valve controls flow through the duct. During filling, a return-gas tube extends into the container's interior. An actuator uses the gas tube as a valve tappet to open and close the liquid valve. As it moves the gas tube up and down, the actuator simultaneously controls a first control-valve that controls flow between the return-gas tube and a gas-chamber. The gas chamber is configured for conducting away return gas forced out of the container's interior by incoming filling product during filling thereof, for imposing a filling pressure in the container's interior, for flushing said container's interior with a flushing gas, or for evacuating the container's interior.
