Abstract: In a filling valve for a counterpressure filling machine for filling containers, such as bottles, cans and the like, comprising a filling valve body including a filling channel, a centering tulip for positioning a container below the filling channel in sealed connection therewith, second channels in said valve body coacting with said filling channel for at least one of evacuating, pressurizing and relieving a container located within said second channels, wherein the improvement comprises each said auxiliary valve includes an axially elongated control bolt located in said filling valve body for opening one of said second channels, said control bolt having a first end located within said filling valve body and a second end located on the outside of said filling valve body, a cam plate located opposite the second end of said control bolt outside of said filling valve body and selectively engageable by the second end of said control bolt, and means associated with said centering tulip for cooperating with said c

Abstract: A filling valve fills liquid from a filling machine vessel into containers. When the filling valve is opened a complete pressure equalization takes place between the vessel and the container to be filled. The container is held in the filling position by a vertically movable centering member. At the end of the filling operation, with the centering member still holding the container, a return gas tube extending into the container can be emptied and the volume of the container above the liquid level can be relieved without any inflow of atmospheric air. Further, the usual expansion below the liquid level is avoided. The centering member along with the filling valve can be lowered into the filling position by a cam disc and a pressure spring and/or assisted by the overpressure within the filling machine vessel. After movement by the cam disc the centering member and filling valve can be pressed against the container opening by the pressure spring and/or the pressure in the vessel.

Abstract: In a rotating machine for filling liquid into bottles in similar containers, a centering member including the filling valve is vertically movable between a lower centering or holding position and an upper release position. The centering member in the lower position seals the bottles during the filling operation. Accordingly, a large number of centering members and filling valves are located next to one another on the periphery of the machine. When the filling operation takes place under counterpressure, there is the danger of bottles breaking and damaging the centering members. Accordingly, a control support block on the machine includes a guide bushing laterally enclosing the centering member in its upper position. The lower section of the centering member projects from the guide bushing in the lower centering position.
