Abstract

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.
