Abstract:
1. An apparatus for filling containers with a liquid filling good, said apparatus comprising a filling element, said filling element comprising a dispensing opening, a centering tulip, a ring seal, a bellows, and a pneumatic device, wherein said dispensing opening provides controlled introduction of said filling good into a particular container having a container opening, wherein said ring seal encloses said dispensing opening, wherein said ring seal is disposed on said centering tulip against which, during operation, said container is pressed, wherein said bellows defines an interior space that is filled with a first pressure medium that has a first pressure, wherein said pneumatic device is exposed to a second pressure medium that has a second pressure, wherein said first pressure medium exerts a first force on said bellows as a result of said first pressure, wherein said second pressure medium exerts a second force on said pneumatic device as a result of said second pressure, wherein either said first pressure medium is an operating medium and said second pressure medium is an auxiliary medium, or said first pressure medium is an auxiliary medium and said second pressure medium is an operating medium, wherein said bellows and said pneumatic device cooperate to apply a press-on force to urge said tulip to press against said container, wherein said press-on force is a sum of a first force component and a second force component, wherein said first component of said press-on force is contributed by said bellows, wherein said second component of said press-on force is contributed by said pneumatic device, wherein at most one of said first component and said second component of said press-on force is fixed by properties of said liquid filling good, wherein a pressure of said auxiliary medium in said pneumatic device can be set for controlling said press-on force, wherein a pressure of said operating medium is not freely variable for controlling said press-on force, wherein controlling said press-on force is selected from a group consisting of varying said press-on force and setting said press-on force, wherein said operating medium is selected from a group consisting of a gaseous operating medium and vaporous operating medium, and wherein said auxiliary medium is selected from a group consisting of a gaseous auxiliary medium and a vaporous auxiliary medium, whereby said press-on force is adjustable by adjusting a force exerted by said auxiliary medium.
