ABSTRACT:
The container filling device includes a first piston slidably mounted within a first cylinder for raising and lowering a nozzle into and out of operative engagement with a container to be filled. A sealing ring is mounted on the lower end of the first piston for sealing engagement with the rim of a container to be filled and a passage is provided for allowing gas pressure within the container to enter the bottom of the first cylinder to provide a pressure differential on the first piston depending upon the diameter of the container. A second piston is slidably mounted for vertical reciprocating movement within a second cylinder and is operatively connected to the first piston. First and second pneumatic pressure supplies are connected to the second cylinder above and below the second piston for regulating the pressure applied between the sealing ring on the first piston and the rim of a container being filled.
