The filling element has a body and has gas and liquid passages extending therethrough from a chamber containing the liquid and gas to a filling head. The filling head is arranged for sealingly engaging the opening in the vessel to be filled. Two concentric conduits on the body extend into the filling opening of the vessel and form therebetween an annular space which is part of the liquid passage while forming an annular space with the filling head which is a part of the gas passage. Valves control the gas and liquid passages and a filler element extending axially through the filler element and on the axis of the inner one of said conduits is arranged to detect the liquid level in the vessel and to control the valves in conformity therewith. An exhaust passage extends from the space on the inner side of the conduit to the gas passage and then to the outside of the filling element and is under the control of an exhaust valve.
