ABSTRACT:
Apparatus for charging solids into a pressurized container having a tubular lock chamber thereon. The apparatus comprises a feed device for supplying solids to the inlet of the lock chamber and a housing mounted adjacent the lock chamber for movement towards and away therefrom; a displacer member is slidably mounted in the housing in axial alignment with the inlet of the lock chamber; a first seal is provided in the housing for sealingly engaging the displacer member, and a second seal is provided on one of the opposed surfaces of the lock chamber and housing. The first seal is axially located along the displacer member at a distance from the end of the housing which exceeds the stroke of the displacer member in its travel between its extended and retracted positions whereby the portion of the displacer member which penetrates into the lock chamber will not come into contact with the first seal.
