Montage von Komponenten zur Treibstoffentlüftung eines Treibstofftanks

摘要

Apparatus and method of assembling an interior fuel systems component (14) suitable for immersion in liquid fuel in a tank to an exterior component (12) of different material weldable to the fuel tank (13). The exterior component (12) is preferably formed of HDPE having a hardness in the range of about RR-40 to RR-80 and has an array of projections (40,42) extending therefrom. The interior component (14) has a corresponding array of radially extending slots having barbed edges for push on connection to the projections. The slots permit sliding movement due to material swelling of the projection on the barbs without loosening of the connection. The internal component (14) is preferably formed of material comprising a member of the group consisting of Polyamide, Polyketone and Polyphenylamide and having a hardness in the range of about R112, such that the barbs deform the lugs to maintain the connection.
