Patent

CA 2286077

A filler neck closure assembly (30) includes a closure apparatus (32) formed to include a pump nozzle-receiving opening (36) and adapted to be mounted on an open mouth of a filler neck (24). A cover (40), pivotally mounted to the closure apparatus (32), is movable between a first position covering the nozzle-receiving opening (36) to seal the filler neck (24) and a second position uncovering the nozzle-receiving opening (36) to allow access thereto. An overcenter leaf spring (42) normally biases the cover (40) toward its first closed position. A tether (94) coupled to the cover (40) has its other end (96) coupled to a filler neck access door (90) so that as the access door (90) is moved from a closed position blocking access to the filler neck (24) to an open position unblocking access to the filler neck (24), the cover (40) is moved from the first position covering the nozzle-receiving opening (36) to the second position uncovering the nozzle-receiving opening (36).

Cette invention se rapporte à un ensemble fermeture de goulot de remplissage (30), qui comprend un dispositif de fermeture (32) conçu de façon à comporter un orifice (36) de réception de la lance de pompe à carburant et prévu pour être monté sur l'embouchure ouverte du goulot de remplissage (24). Un couvercle (40), monté pivotant sur le dispositif de fermeture (32), peut passer d'une première position couvrant l'orifice (36) de réception de la lance, afin d'obturer hermétiquement le goulot de remplissage (24), à une seconde position découvrant l'orifice (36) de réception de la lance, pour permettre l'accès à cet orifice. Un ressort à lame à bascule (42) sollicite en position normale le couvercle (40) dans sa première position fermée. Un lien souple (94) couplé au couvercle (40) est relié par son autre extrémité (96) à une porte d'accès (90) du goulot de remplissage, pour que cette porte d'accès (90) passe d'une position fermée bloquant l'accès au goulot de remplissage (24) à une position ouverte libérant l'accès audit goulot de remplissage (24), ledit couvercle (40) se déplaçant de la première position couvrant l'orifice (36) de réception de la lance à la seconde position découvrant ledit orifice (36) de réception de la lance.
