Patent ID: 8820366

Claim:
An apparatus for filling containers, including cans and bottles, with a liquid product, wherein said container has an opening surrounded by an opening edge, said apparatus comprising a filler element, said filler element comprising a filler element housing, a discharge opening, a container contact surface, a tulip, a cylinder, a chamber, a source of pressure connected to said chamber, wherein said chamber is disposed within said cylinder, wherein a wall of said chamber is defined by an upper surface of said tulip, wherein said tulip defines a piston that is guided for movement in said cylinder, wherein said piston extends between said container contact surface and said upper surface, wherein a total gas pressure acting on said tulip is a sum of pressure from said source of pressure in said chamber and ambient air pressure, where said discharge opening is disposed for controlled introduction of said liquid product into said container, wherein said container contact surface is disposed at a bottom of said tulip, wherein said tulip is movable relative to said housing between a raised position and a lowered position, wherein a force generated by said pressure in said chamber causes said tulip to transition into said lowered position, wherein a value of said pressure controls contact pressure against an opening edge of a container, and wherein the tulip is guided so as to be displaceable with a part region in the cylinder chamber.
