ABSTRACT:
In a container filling apparatus having a plurality of revolving charging cylinders and respective pistons by which a fluid filling material supplied into the cylinders with their pistons at the limit end of their intake strokes is subsequently pushed out of the cylinders and through nozzles to fill respective containers at a filling position, the containers being preparatorily positioned on respective revolving platforms, the piston rod of each of the charging cylinders can be locked at the start of its intake stroke by a respective locking mechanism when the mechanism, as it revolves with the cylinder, contacts and is actuated by a stationary actuating device operated in accordance with a detection signal generated by a monitoring device. When this monitoring device detects the absence of an empty container from its preparatory position on any platform, it generates the detection signal to lock the corresponding piston rod thereby to prevent containerless discharging of the filling material. A stationary resetting cam operates to unlock this piston rod when it has revolved past the filling position.
