Abstract
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.
