Abstract
An apparatus for filling containers with a product, includes a product supply, a pre-filling chamber having a controlled outlet, a movable sealing arrangement having a closed position for isolating the product supply from the pre-filling chamber, and a displacer arrangement that extends into the pre-filling chamber and that has an elastically deformable wall. The displacer arrangement is interactively connected to a control medium in such a way that an elastic volume change in the displacer arrangement changes a volume of the pre-filling chamber, thereby permitting control over an amount of product delivered through the outlet.
Claims21
An apparatus for filling containers with a material, said apparatus comprising a product supply, a pre-filling chamber, a movable sealing-arrangement, a displacer arrangement, an elastically-deformable wall, a controllable outlet, a control surface, and a dual-piston arrangement comprising an inner piston and an outer piston, wherein said pre-filling chamber is isolatable from said product supply, wherein said pre-filling chamber comprises said controllable outlet, wherein said movable sealing-arrangement has a closed position for isolating said product supply from said pre-filling chamber, wherein said displacer arrangement is extendible into said pre-filling chamber, wherein said displacer arrangement comprises said elastically-deformable wall, wherein said displacer arrangement is interactively connected to said control surface in such a way that deformation of said elastically-deformable wall causes a volume change in said displacer arrangement that changes a volume of said pre-filling chamber, thereby permitting control over an amount of product delivered through said outlet, wherein said inner and outer pistons are concentric, and wherein said inner and outer pistons are arranged to interact telescopically.
An apparatus for filling containers with a material, said apparatus comprising a product supply, a pre-filling chamber comprising a controllable outlet, a movable sealing-arrangement that transitions into a closed position in which said product supply is isolated from said pre-filling chamber, said movable sealing-arrangement comprising concentric inner and outer pistons that are arranged for telescopic interaction with each other, a displacer arrangement that extends into said pre-filling chamber and that comprises an elastically-deformable wall, and a control surface that is interactively connected to said displacer arrangement so as to cause deformation of said wall, said deformation resulting in an increase and then a decrease in volume of said displacer arrangement while said displacer arrangement is within said pre-filling chamber, wherein an extent of said increase in said volume of said displacer arrangement results in a corresponding decrease in volume of said pre-filling chamber, which then results in ejection of a corresponding volume of said material through said controllable outlet.
