Abstract
A method can be used to form a plastic filler neck for a vehicle. The method includes providing a fuel injection pipe comprising a polyamide material containing nanoclay and having a single layer structure in cross-section, inserting and fastening a retainer into an internal space of a tip of the fuel injection pipe to support a refueling gun, directly fastening a cap holder to the tip of the fuel injection pipe, and mounting an air drain casing to an outer diameter portion of the cap holder fastened to the fuel injection pipe using a mounting bracket.
Claims19
A method of forming a plastic filler neck for vehicles, the method comprising:
- providing a fuel injection pipe comprising a polyamide material containing nanoclay and having a single layer structure in cross-section;
- inserting and fastening a retainer into an internal space of a tip of the fuel injection pipe to support a refueling gun;
- directly fastening a cap holder to the tip of the fuel injection pipe, wherein an inner diameter surface of a rear end of the cap holder and an outer diameter surface of the tip of the fuel injection pipe are integrally fused to each other;
- and
- mounting an air drain casing to an outer diameter portion of the cap holder fastened to the fuel injection pipe using a mounting bracket,
- wherein the air drain casing includes:
- a seating groove formed on its bottom to be pressed against an outer diameter surface of the cap holder;
- a locking protrusion formed on its front;
- and
- an air inlet formed on its rear surface and configured to communicate with outside air, and
- wherein the mounting bracket comprises a pair of tightening plates, each tightening plate having a tightening groove formed on its inner side to be pressed against the outer diameter surface of the cap holder and a locking groove formed at its upper end for fastening with the locking protrusion of the air drain casing.
