Filler neck for filling a fluid system

Abstract

A filler neck for filling a fluid system, especially for filling a radiator assembly or an engine coolant system is provided. The filler neck avoids breaking of joints and waiving of leak tests by a filler tube and a filler beginning connected with the filler tube.

1 . A filler neck for filling a fluid system, the filler neck comprising:
 a filler tube; and   a filler beginning connectable with the filler tube,   wherein the filler tube and the filler beginning are formed in one piece,   wherein the filler tube is curved and the filler beginning is directed approximately perpendicular to a fluid system opening,   wherein the filler beginning has a larger diameter than a diameter of the filler tube,   wherein a flanged socket is fixed substantially perpendicular to the filler beginning, and   wherein the filler neck is configured for filling a radiator assembly or an engine coolant system.   
     
     
         2 - 8 . (canceled) 
     
     
         9 . An engine coolant system comprising:
 a radiator having an opening lying in a first plane;   a filler neck extending from the radiator opening, the filler neck comprising a curved filler tube having an outer diameter of a first size and a cylindrical filler beginning integrally formed with the filler tube at an end of the filler tube opposite the radiator, the filler beginning having an outer diameter of a second size greater than the first size, the filler tube including a flared portion at the filler beginning, the outer diameter of the filler tube increasing from the first size to the second size along the flared portion.   
     
     
         10 . The engine coolant system according to  claim 9 , wherein the outer diameter of the flared portion increases continuously from the first size to the second size. 
     
     
         11 . The engine coolant system according to  claim 10 , wherein the filler beginning includes an end lying in a second plane substantially perpendicular to the first plane. 
     
     
         12 . The engine coolant system according to  claim 11 , wherein a radius of curvature of the filler tube is constant from the radiator opening to the filler beginning. 
     
     
         13 . The engine coolant system according to  claim 12 , including a flanged socket projecting perpendicularly from the filler beginning. 
     
     
         14 . The engine coolant system according to  claim 13 , wherein the filler beginning includes a projecting flange at a location spaced from the filler tube. 
     
     
         15 . The engine coolant system according to  claim 9 , wherein a radius of curvature of the filler tube is constant from the radiator opening to the filler beginning. 
     
     
         16 . A filler neck for filling a fluid system, the filler neck comprising:
 a filler tube portion and a filler beginning portion integrally formed with the filler tube portion, the filler tube portion having a first end connectable to an opening in the fluid system and a second end spaced from the first end, the filler neck including a flared portion between the filler tube portion second end and the filler beginning portion, the filler tube portion having a substantially constant first outer diameter, the filler beginning portion being cylindrical and having a substantially constant second outer diameter greater than the first outer diameter and the flared portion having an outer diameter that increases from the first outer diameter at the second end of the filler tube portion to the second outer diameter at the filler beginning portion, the filler tube portion being arc shaped and having a substantially constant radius of curvature from the first end to the flared portion and extending through a 90 degree arc, the filler beginning portion including a flanged socket projecting perpendicularly therefrom and an end flange at an end of the filler beginning portion opposite the filler tube portion.
