Abstract

A filling element for counterpressure filling machines. The element has a controlled pressurized gas valve arrangement for generating a gas pressurization in a pressed-on container, which is to be filled, prior to introducing liquid into the container. The filling element also includes a liquid flow valve, which opens under the effect of a spring upon termination of pressurization, a valve actuating device, which closes the liquid flow valve against the effect of the opening spring, and an electrical switching member for generating a closure-control signal for the valve actuating device to occupy the closed position upon contact with the liquid rising in the container. In addition to the electrical switching member, a further control switch is associated with the valve actuating device and is controllable by a device, which is independent of the switching member in such a way that when liquid contact is lacking at the switching member the signal therefrom, or an additional closure control signal, is maintained for the valve actuating device at most until termination of the pressurizing.
