Abstract:
An adaptor for a fill pipe of a container to be filled, said fill pipe having an enlarged end for receiving said adaptor therein, said adaptor having a first end, a second end and a frusto-conical section between said first end and said second end, said container having a vacuum inlet port separate from said fill pipe, said vacuum inlet port connected to a vacuum chamber fitting adjacent said first end of said adaptor, said first end having a locking ring for removably locking a quick release coupling of an automated filling nozzle thereto, said filling nozzle having a vacuum responsive valve means therein, said frusto-conical section receiving a discharge end of said filling nozzle substantially contiguous with an inside surface thereof establishing a narrow space between said discharge end and said frusto-conical section such that the velocity of fluid being discharged from said discharge end of said nozzle creates a vacuum in said narrow space and said vacuum chamber, said vacuum actuating said vacuum responsive valve means to retain a manually actuated filling valve in said nozzle in an open position in the presence of vacuum in said vacuum chamber and closing said filling valve when the level of liquid in said container reaches said vacuum inlet port thereby increasing said vacuum to said vacuum responsive valve means, said second end of said adaptor having a safety closure integral therewith to reduce spillage of liquid from said container upon tipping of said container said safety closure moved to an open position by a means for operating disposed remote from said safety closure, said means for operating actuated by said discharge end of said filling nozzle when said filling nozzle is inserted into said fill pipe adaptor.
