Definitions

  • This application claims priority to British Patent Application Serial No 9804948.9, filed March 10, 1998, which is expressly incorporated by reference herein
  • This invention relates to a fuel cap for a filler neck of a tank such as the fuel tank of a motor vehicle of the type in which lugs on the fuel cap are brought into engagement with complimentary formations on the filler neck by relative angular movement about the central axis of the filler neck
  • the invention is particularly, but not exclusively, applicable to fuel caps of the type having a bayonet connection to the filler neck
  • a fuel cap of the type described above has a compression spring adapted to engage with the filler neck so as to cause outward movement of the fuel cap relative to the filler neck in the event that the lugs on the fuel cap are not in engagement with the complimentary formations on the filler neck.
  • the compression spring may be arranged to cause displacement of the fuel cap to a position which is visibly' proud of the vehicle body.
  • the spring may be arranged to cause outward displacement of the fuel cap to such an extent that the flap cannot be closed.
  • Fig 1 is a perspective view of a fuel cap in accordance with the invention showing the fuel cap aligned with, but spaced apart from, an end of a filler neck,
  • Fig 2 is a side view of the fuel cap and filler neck of Fig 1 with portions broken away, showing the fuel cap fully engaged with the filler neck, and
  • Fig 3 is a side view of the fuel cap and filler neck of Fig 1 with portions broken away, showing the fuel cap inserted into the filler neck but not secured "therein
  • FIG. 1 shows a fuel tank closure system 10 including filler neck 12 of a fuel tank 13 and a fuel cap 14 engageable with filler neck 12
  • Fuel cap 10 includes a closure 16, a seal 18 coupled to closure 16, and a compression sp ⁇ ng 20 coupled to closure 16
  • Closure 12 includes a core 22 positioned to extend through a passageway defined by spring 20 and a handle 24 coupled to core 22
  • Core 22 includes a body member 26 sized to be received in filler neck 12, a flange 28 which projects over an end 30 of filler neck 12, and a locking bar 32 having lugs 34 which engage with complementary formations 36 on filler neck 12 When lugs 34 are in engagement with complementary formations 36 of filler neck 12, seal 18 on closure 16 engages with a tapered formation 36 on end 28 of filler neck 12, as shown m Fig 2
  • compression sp ⁇ ng 20 engages flange 28 of closure 12 and an axially outer surface 29 on end 30 of filler neck 12
  • Compression sp ⁇ ng 20 comprises a plastics molding having a ⁇ ng-shaped upper head member 40 abutting against flange 28, a ⁇ ng-shaped lower foot member 42 abutting against end 30 of filler neck 12, and a integrally molded flexible connector 44 that interconnects head and foot members 40, 42
  • Flexible connector 44 includes a pair of diametrically spaced-apart flexible body members 46 that each include a first pair of curved arms 48 coupled to head member 40, a second pair of curved arms 50 spaced apart from first pair of arms 48 and coupled to foot member 42, and a web member 52 -3- coupled to and positioned to lie between first and second pair of curved arms 48, 50.
  • First pair of arms 48 are convex in an axially inner direction along a central axis 54 of filler neck 12 and second pair of arms 50 are convex in an axially outer direction along central axis 54.
  • Filler neck 12 includes central axis 54 and an inner side wall 56 defining a hollow 58 in communication with an interior region 60 of fuel tank 13. If closure 16 is in an axially inner position along central axis 54 so that core 22 is fully inserted into hollow 58 of filler neck 12 and lugs 34 on locking bar 32 are in an engaged position so that lugs 34 are in engagement with complementary formations 36 on filler neck 12, spring 20 is compressed so that flange 28 is in close proximity to end 30 of filler neck 12, as shown in Fig. 2.
  • closure 16 is movable between the axially inner position and an axially outer position and spring 20 moves flange 28 to a spaced-apart position from end 30 of filler neck 12, with closure 16 and seal 18 moved to an axially outer position along central axis 54, as shown in Fig. 3.

Abstract

L'invention concerne un système de fermeture (10) pour réservoir de carburant qui comprend un col de remplissage (12) et un bouchon de réservoir (14) qui met en prise le col de remplissage (12). Le bouchon de réservoir (14) comprend une fermeture (16), un joint d'étanchéité (18) couplé à la fermeture (16) de manière à mettre en prise le col de remplissage (12) et un ressort (20). La fermeture (16) comprend une poignée (24) et un tenon (34) qui met en prise le col de remplissage (12). La poignée (24) est conçue pour mettre le tenon (34) soit en position d'accouplement, lorsque la fermeture (16) se trouve en une position axiale intérieure, soit en position de désaccouplement, lorsque la fermeture (16) est libre de se déplacer entre les positions axiales intérieure et extérieure. Le ressort (20) déplace la fermeture (16) par rapport au col de remplissage (12) de manière à la mettre dans la position axiale extérieure lorsque le tenon (34) se trouve en position de désaccouplement.
