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.

An extractor tube assembly for use with a container which includes sidewalls, comprising: a. a valve neck for attaching said extractor tube assembly to the container, said valve neck comprising an upper and lower surface; b. a valve body retained within said valve neck; c. a valve housing member attached to said valve body adjacent to the lower surface of said valve neck, said valve housing member depending from said valve body and including a depending basket portion having at least one opening therein; d. a first valve assembly including a first valve seat and a movable first valve member, both seated within said valve body; e. an elongated siphon tube attached to said moveable first valve member; f. retaining means for retaining said moveable first valve member against said first valve seat to maintain said first valve assembly in a normally closed position; g. a second valve assembly seated within said first valve assembly; h. said elongated siphon tube further comprising an elongated cylindrical portion and a widened neck portion at the top of said elongated siphon tube; and i. deflector means comprising a deflector plate retained between said widened neck portion of said elongated siphon tube and said retaining means; j. whereby when said first valve assembly is in an opened position, a flow path for fluid is defined such that fluid enters the extractor tube assembly, travels in the flow path defined between said first valve seat and said first valve member, is deflected by said deflector means and then travels directly out said at least one opening in said depending basket portion of said valve housing member and against said sidewalls of the container and thereafter into the container.
