Abstract
In packing machines of the type which manufacture packing containers with liquid contents a filling pipe with a valve arrangement situated at the outlet end is frequently used. The valve arrangement that is described comprises a movable valve element which is manoeuvred with the help of pressure variations in the filling pipe. The movable valve element is cup-shaped and is adapted so that it is lifted through excess pressure in the filling pipe from a fixed seat so that an annular discharge opening results.
