  • Patent number: 5791387
    Abstract: To securely retain a valve flap (10) against an opening (8) in a fill end stub for liquid fuel, typically unleaded gasoline, a pivotable engagement finger (15, 35) is engageable with the flap and held against the opening by an operating system (18, 28, 38) operable by the vehicle operator, for selective engagement of the finger (15, 35) against the underside of the flap (10) to selectively press the flap against the opening and close the opening, or to permit pivoting of the flap away from the opening if an appropriate gasoline fill-in nozzle is pressed against the flap.

  • Patent number: 5735322
    Abstract: To form an easily manufactured and installed end piece and nozzle receptor (1) for a fill pipe of a fuel tank of a motor vehicle, adapted to receive a fuel dispensing nozzle (14) of a specific type, for example for lead-free gasoline, the nozzle receptor is a single, unitary element (1) of electrically conductive sheet metal, preferably aluminum or stainless steel. It is formed with an inner thread (5) to receive a fuel cap and, just beyond, formed with an extended sealing flange (6), adapted to fit, sealingly, against an end portion (8) of the fill pipe (4). The seal can be obtained, for example, by welding the fill pipe and the nozzle receptor, preferably along a welding bead (7). A circumferential apron (9) extends from the flange (6), the apron having a height varying along its circumference so that it can fit against the body or chassis (11) of the motor vehicle, and be attached thereto along a laterally projecting attachment flange (10).

  • Patent number: 4936611
    Abstract: A latch mechanism including: a mounting plate carrying a slot having a bottom and mouth, the latch mechanism having disposed therewith a pivotably biased pawl mechanism comprising a top arm portion for pivoting from a position over the slot to a position spaced from it, the pawl having a bottom arm portion, and a follower mechanism for positioning the pawl with respect to the slot of the mounting plate, the pawl mechanism having a primary pivot about which it normally pivots or rotates and a secondary safety pivot about which the pawl is able to rotate if the primary pivot breaks and which secondary safety pivot does not interfere with any normal operation motion, the latch mechanism having disposed therewith a ratchet mechanism biased for rotation and carrying a notch having a mouth and control mechanism for controlling the position of the pawl mechanism with respect to the slot when the control mechanism of the ratchet engages the follower mechanism of the pawl, the latch mechanism having disposed therewith
