A filling element for single- and multi-chamber counterpressure filling machines. The filling element includes a filling tube which projects downwardly from a filling element body into a pressed-on bottle or container to be filled. The filling element also includes a switching member installed in the region of the filling tube for controlling the liquid flow valve, arranged inside the filling element, to close this valve when the desired filling level of liquid in the container is obtained. The filling tube is provided with a filling tube head installed from below into a suitable recess in the filling element body, and the filling tube head, with a downwardly directed shoulder, is stepped relative to the actual filling tube part. The switching member is an electrical conductor which is electrically insulated relative to the filling tube, and is placed on the outer side of the filling tube. The electrical connection device for the switching member includes an electrically insulated contact pin which is axially shiftably supported in the filling element body. The contact pin is sealed relative to the filling element body, and the end surface of the pin is pressed into electrical contact against the switching member; simultaneously, the end of the pin engages under the shoulder of the filling tube and is retractable from the region of the shoulder.

1. A filling element, for single- and multi-chamber counter-pressure filling machines, for introducing liquid into a container, said filling element comprising: a filling element body; a filling tube having a main portion and a filling tube head, said filling element body being provided with a suitable recess for receiving said filling tube head therein from below so that said main portion of said filling tube projects downwardly from said filling element body into a pressed-on container to be filled, said filling tube head being provided with a downwardly directed shoulder, so that said filling tube head is stepped relative to said main portion of said filling tube; a liquid flow valve arranged in said filling element body and operatively associated with said filling tube; a switching member installed in the region of said filling tube for closing said liquid flow valve when the desired filling level of liquid in said container is obtained, said switching member being an electrical conductor which is placed on the outer side of said filling tube and is electrically insulated relative thereto; and an electrical connection device for switching member, including an electrically insulated contact pin which is axially displaceably supported in said filling element body and is sealed off relative thereto, said contact pin having a first end and a second end, said first end of said contact pin including an end face and an adjusting peripheral surface which is perpendicular to said end face, said end face being pressable into electrical contact against said switching member, and said peripheral surface adjoining said end face being engageable under, and retractable from, the region of said shoulder of said filling tube head. 2. A filling element according to claim 1, in which said shoulder, and at least that portion of the outer surface of said filling tube head adjacent said shoulder, are provided with an electrically insulating layer. 3. A filling element according to claim 1, in which at least that portion of the outer surface of said filling tube head adjacent said shoulder is provided with an electrically insulating layer which extends to said shoulder; in which said switching member is placed on the outer side of said filling tube and on said shoulder; and in which said electrical contact between said switching member and said contact pin pressed thereagainst is established by means of said end face and said peripheral surface of said first end of said contact pin. 4. A filling element according to claim 2 or 3, in which said contact pin is axially displaceably supported in, and is sealed off relative to, a part of said filling element body comprising electrically insulating material. 5. A filling element according to claim 2, in which said contact pin, except for said end face of said first end thereof, is provided with an electrically insulating surface layer. 6. A filling element according to claim 3, in which said contact pin, except for said end face and said adjoining peripheral surface of said first end thereof, is provided with an electrically insulating surface layer. 7. A filling element according to claim 1, in which said contact pin is provided with a spring which presses said pin against said switching member, and with a lifting device which acts counter to said spring and is actuated externally of said filling element body, said lifting device having a length of effectiveness which is greater than the width of said shoulder. 8. A filling element acording to claim 7, in which said lifting device comprises a rotating-wedge device which is provided with a control lever, said contact pin being axially displaceably connected to said control lever.
