Fluid flow device including a parallel passageway flow straightener

Claim 1

A FILLING SPOUT FOR SILENTLY DISCHARGING LIQUID INTO A RECEPTACLE TO FILL THE SAME COMPRISING: (A) MEANS DEFINING A RELATIVELY LOW VELOCITY DISCHARGE NOZZLE DISCHARGING TO A RECEPTACLE, (B) MEANS DISPOSED IN SAID NOZZLE TO ABSORB THE TURBULENCE IN A FLOW OF LIQUID THERETHROUGH AND TO STRAIGHTEN AND DIRECT SAID LIQUID FLOW THERETHROUGH INTO ONE SMOOTH STREAM AT FULL FLOW MOTION, (C) SAID LATTER MEANS INCLUDING A PLURALITY OF PARALLEL PASSAGEWAYS EXTENDING LONGITUDINALLY OF SAID NOZZLE, (D) SAID PASSAGEWAYS BEING RADIALLY DISPOSED WITHIN THE CIRCUMFERENCE OF SAID NOZZLE, (E) AND A CONCAVO-CONVEX PERVIOUS MEANS EXTENDING ACROSS THE DISCHARGE END OF SAID NOZZLE DOWNSTREAM OF SAID PASSAGEWAYS TO INSURE A SMOOTH, UNINTERRUPTED STREAM DURING LOW FLOW RATES, (F) SAID PERVIOUS MEANS BEING CONCAVED IN THE DIRECTION OF LIQUID FLOW THERETHROUGH WHEREBY THE STREAM ORIGINATES AT THE LOWERMOST POINT OF SAID PERVIOUS MEANS UPON THE INITIATION OF THE LIQUID FLOW, AND WHICH STREAM MERELY BECOMES LARGER AS FLOW IS INCREASED, SAID STREAM FORMING A CLEAR SYMMETRICAL COLUMN EXTENDING BETWEEN THE SPOUT END AND THE POOL COLLECTING IN THE RECEPTACLE SO THAT THE LIQUID FALLING IN SAID COLUMN SILENTLY FLOWS INTO SAID POOL.
