An electrically controlled filling element, for filling machines, having one or more actuating devices for one or more shutoff valves, which are disposed in the gas-conveying systems of the filling element and are actuated for control of the various filling processes, and/or for the valve actuating device of one or more liquid flow valves. These actuating devices are made insensitive to the penetration of moisture, for example cleaning liquid, by providing one or more of the actuating devices with a diaphragm which is operated by pressure medium, and by disposing the respective pressure medium control valves which control the supply of pressure medium separate and at a distance from the other parts of the filling element at a location of the filling machine which is protected from the entry of liquid. An additional shielding of the pressure medium control valve can be undertaken by providing a housing therefor.

A filling element for filling machines, said filling element including liquid introduction means which leads to the interior of a container pressed onto said filling element so that it can be filled; said liquid introduction means has at least one liquid flow valve, which is under the influence of an opening spring and of an electrically controlled valve actuating device which acts counter to said opening spring; also provided is at least one gas-conveying system having at least one electrically controllable shutoff valve; the improvement comprises: a respective electrically controlled actuating device for each of said shutoff valves, with at least one of said actuating devices of said at least one shutoff valve and of said at least one liquid flow valve containing, as an element which generates actuating force for the functioning of its valve, a respective diaphragm which is operated by pressure medium; pressure medium supply means for supplying said pressure medium to each of said diaphragm; and pressure medium control valve means for said supply means, with said control valve means being mounted on said machine at a location which is separate and at a distance from other parts of said filling element, and which is protected from the entry of liquid.
