Conducting System For a Filling Pipe

Abstract

A conducting system for a fuel tank filling pipe, including a filling bowl made of a conducting plastic, a filling nozzle guide, also made of a conducting plastic, provided with deformable teeth, and in direct contact with the filling bowl, and a metal head. The bowl and the guide are inserted into the metal head such that the teeth are in permanent radial contact with the metal head when the bowl and the guide are mounted in the filling pipe.

       11 . A conducting system for a fuel tank filling pipe, comprising:
 a filling bowl made of a conducting plastic, with deformable teeth;   a filling nozzle guide, also made of a conducting plastic, and in direct contact with the filling bowl; and   a metal head;   wherein the bowl and the guide are inserted into the metal head such that the teeth are in permanent radial contact with the metal head when the bowl and the guide are mounted in the filling pipe.   
   
   
       12 . The system according to  claim 11 , wherein the filling bowl and the guide form a one-piece unit. 
   
   
       13 . The system according to  claim 12 , wherein the material of the unit is conducting high-density polyethylene (HDPE). 
   
   
       14 . The system according to  claim 12 , wherein the unit is produced using an injection-molding technique. 
   
   
       15 . The system according to  claim 11 , wherein the bowl/guide unit includes a metal ring on its periphery. 
   
   
       16 . The system according to  claim 15 , wherein the bowl or the unit is overmolded onto the metal ring. 
   
   
       17 . The system according to  claim 11 , wherein the filling pipe comprises stamped portions corresponding to the teeth and is configured to support axially and prevent rotation of the bowl/guide unit in the pipe. 
   
   
       18 . The system according to  claim 11 , wherein the teeth give the bowl/guide unit a diameter greater than that of an opening in the metal head configured to house the bowl/guide unit. 
   
   
       19 . The system according to  claim 11 , wherein further comprising a seal situated on the filling pipe in a position to be compressed by the metal head once the system is assembled. 
   
   
       20 . A process for producing a conducting system according to  claim 11 , comprising:
 providing the filling pipe with a seal;   force-fitting a bowl/guide unit of one part, or of two parts assemble together, and provided with deformable radial teeth, into the fitting pipe; and   force-fitting the whole into a metal head, simultaneously compressing both the seal and the teeth.
