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. A seal extends between the guide bushing and the centering member and is spaced upwardly from the lower section of the centering member so that in the upper position of the centering member the lower section does not contact the seal.
