Abstract

Abstract A concentric well-type extractor tube having two concentric valves retained in a valve neck for filling containers, such as beer kegs, with pressurized beverages. The length of the valve neck is reduced so that the bottom of the valve neck is horizontally aligned with the top of a movable first valve assembly. The side openings of the depending basket portion of the extractor tube are raised to a position adjacent the first valve assembly. Therefore, beer filling an inverted keg can pass directly between a first valve seat and movable first valve member of the first movable valve assembly and thereafter through the openings in the basket and into the keg. This substantially shortens the beer flow path and eliminates the passage of beer through a constricted area found in prior art extractor tubes. Also, a transverse deflector plate serves to deflect beer from the center of the keg to the sidewalls, thereby substantially reducing turbulence during filling. The deflector plate can be retained on the siphon tube portion of the extractor tube, can be located within the depending basket portion of the siphon tube, or can be located on the top of the lip of the siphon tube adjacent the first valve seat, either as an extension of the lip or wedged between the top of the lip and bottom of the first valve seat.
