A filling element for filling containers includes a housing having a liquid channel, a connection for feeding liquid into the channel, a discharge port for discharging liquid into a container provided in a sealed position on the filling element, a valve in the channel between the connection and the port, an actuator for opening and closing the channel, a gas path for pre-stressing the container's interior with gas and returning displaced gas, a switching valve in the gas path, the valve being switchable by the actuator between a first state for use while pre-stressing and a second switched state for use with displaced gas, wherein in the first state, the gas path has a first effective flow cross section, and in the second state, the gas path has a second effective flow cross section, the second effective flow cross section being different from the first effective flow cross section. |
