Abstract
A fuel tank filler neck apparatus includes a filler neck and a filler neck component mounted in a fuel-conducting passageway formed in the filler neck. The filler neck component could be a fuel tan inlet check valve or a closure cap mount.
Claims20
A fuel tank filler neck apparatus comprising
- a filler neck comprising a side wall and a filler neck low-permeation layer coupled to an interior surface of the side wall and configured to define a boundary of a fuel-conducting passageway extending through the filler neck, and
- a filler neck component comprising a base arranged to lie in the fuel-conducting passageway and a component low-permeation layer coupled to an exterior surface of the base, wherein the filler neck low-permeation layer is made of a first material, the component low-permeation layer is also made of the first material, and the component low-permeation layer is bonded to the filler neck low-permeation layer at a bond joint to retain the filler neck component in a fixed position in the fuel-conducting passageway to establish a low-emission union of the component and filler neck low-permeation layers to provide means for blocking permeation of liquid fuel and fuel vapor extant in the fuel-conducting passageway to atmosphere surrounding the side wall through the component and filler neck low-permeation layers.
A fuel tank filler neck apparatus comprising
- a filler neck component formed to include a fuel-conducting conduit,
- an annular component low-permeation layer coupled to and arranged to surround an annular exterior surface of the filler neck component,
- an annular filler neck low-permeation layer arranged to surround the annular component low-permeation layer and bonded to the component low-permeation layer at a bond joint to establish a low-emission union of the component and filler neck low-permeation layers to provide means for blocking permeation of liquid fuel and fuel vapor extant in a fuel-conducting passageway formed in the annular component low-permeation layer to atmosphere surrounding the filler neck low-permeation layer, and
- an annular side wall coupled to and arranged to surround the annular filler neck low-permeation layer to form a filler neck containing the filler neck component.
1 more element
A fuel tank filler neck apparatus comprising
- a filler neck having an internal low-permeation layer defining a fuel-conducting passageway and
- a filler neck component having an external low-permeation layer bonded to the internal low-permeation of the filler neck to establish a low-emission union therebetween, wherein each of the internal and external low-permeation layers are made of a first material.
