Filling device with interchangeable valve member for cans of different diameters

摘要

A filling device for cans is provided with a cylindrical filling tube having a valve member moveable coaxially therein with complementary projections on the interior surface of the filling tube and the valve member to define a fluid shut off and to define related surfaces to provide the circumferential laminar flow of fluid into a can whereby the residual fluid remaining after the closing of the valve will not drip due to surface tension. A cylindrical valve member is slidably mounted in a housing surrounding the filling tube and is provided with a sealing ring at the lower end for engaging the rim of a can to be filled. Depending on the diameter of the cylindrical valve member a bearing sleeve having an appropriate radial thickness can be inserted in the housing to take up the slack.
