Fuel filler systems and methods of assembling same

摘要

Systems and methods for assembling a fuel filler system for use in a vehicle are provided. The fuel filler system includes a closure device assembly and a fuel filler tube. A circumferential rim extends radially outwardly from a first end of the fuel filler tube. The rim has a non-planar cross-sectional shape. The fuel filler system also includes at least one catch member that extends from an inner surface of the closure device assembly. A seal member encircles a portion of the closure device assembly, and is axially spaced apart from the at least one catch member. After the closure device assembly is coupled to the fuel filler tube, the circumferential rim is axially captured between the at least one catch member and the seal member.

主权项

1. A fuel filler system for use in a motor vehicle, said fuel filler system comprising:
a fuel filler tube including a tube end and a longitudinal axis; a closure device assembly coupleable with said tube end, wherein said closure device assembly comprises an inner collar and an outer cover; a circumferential rim extending radially outward from said tube end, said circumferential rim defining a non-planar cross-sectional shape and comprising a curved sealing surface extending radially outward from said tube end; at least one catch member extending from an inner surface of said outer cover of said closure device assembly, wherein said outer cover and said inner collar define an annular gap that receives said circumferential rim after said closure device assembly is coupled to said fuel filler tube; and a seal member circumferentially coupled to a portion of said closure device assembly via a circumferential notch defined in a radially outwardly-facing surface of said inner collar, and axially spaced apart from said at least one catch member, wherein said circumferential rim is axially captured between said at least one catch member and said seal member such that said sealing surface sealingly engages said seal member.
