Abstract
The filling valve in a counterpressure filling apparatus for admission of liquids into bottles or other types of containers having open upper ends is provided with a sleeve which can descend toward an empty container below the valve and carries a deformable internal annular sealing element which is movable into sealing engagement with the external surface of the open end to center the container. The sealing element is thereupon acted upon by a gaseous fluid to bear against the external surface and to establish a reliable seal during subsequent or simultaneous admission of a pressurized gaseous fluid which precedes the admission of a metered quantity of liquid whereby the liquid expels the gaseous fluid along the same path which serves for admission of pressurized gaseous fluid into the container.

Apparatus for filling bottles and like containers of the type including an upper end having a first outer diameter and provided with a fluid-admitting inlet and a larger-diameter portion adjacent said upper end and having an external surface, comprising a sleeve having an open lower end arranged to admit a container;
- a fluid conveying conduit which discharges fluid into said container, said conduit having a discharge end within said sleeve;
- means for moving said sleeve up and down away from and around a container below said sleeve;
- a deformable annular sealing element provided in said sleeve and designed to establish a seal around the external surface of the larger-diameter portion when a container extends into said sleeve;
- and fluid-operated means for biasing said deformable sealing element against the external surface of the larger-diameter portion of a container which extends into said sleeve.
