A method and filling element for dispensing a liquid into a bottle or some other container. A filling element is provided with a liquid flow valve and a delivery opening via which, in a filling phase, with the liquid flow valve open, the liquid that is to be dispensed flows into a container that is to be filled through an opening thereof. In a rinsing phase that precedes the filling phase, the interior of the bottle is supplied with a rinsing gas via a tubular member that extends through the container opening into the interior thereof. The rinsing gas is discharged into the container from a gas conduit opening provided at the bottom of the tubular member. This discharge opening is in the form of an annular opening that extends concentrically about the filling element axis. By introducing the rinsing gas into the interior of the container via this annular opening, the quantity of residual air that remains after rinsing is considerably reduced despite a short rinsing time.
In a method of dispensing liquid into bottles, cans, or other containers, using a filling element that has a filling element axis, a liquid flow valve, an oppositely disposed surface and a delivery opening, via which, in a filling phase, with said liquid flow valve open, said liquid that is to be dispensed flows into a container that is to be filled through an opening thereof, whereby in a rinsing phase that precedes the filling phase, the interior of said container is supplied with a rinsing gas via a tubular member that extends through said opening of said container into the interior thereof, with said rinsing gas being discharged into said container from a gas conduit including an opening provided at a bottom end of said tubular member, comprising the improvement therewith including the step of:
In a filling element for filling machines with a filling phase for dispensing a liquid into bottles, cans, or other containers, with said filling element having a filling element axis and including a liquid flow valve that has a valve body that can be moved back and forth between a position that blocks said liquid flow valve and a position that opens said liquid flow valve, with said filling element being provided, in the vicinity of said filling element axis, with a delivery opening via which, in said filling phase, with said liquid flow valve open, said liquid that is to be dispensed flows into a container that is to be filled through an opening thereof, and with said filling element also being provided with a tubular member that projects downwardly beyond said filling element and that includes an opening of a gas conduit provided at its bottom end, spaced from said filling element and in the vicinity of said filling element axis, said opening of the gas conduit being formed in said tubular member and being connectable via a control valve arrangement with a source of pressurized rinsing gas, comprising the improvement therewith wherein:
