Abstract
A closure device for tank filler necks in motor vehicles. The closure device has the object of configuring the tank filling operation to be more comfortable.

Claims22
A closure device for a tank filler neck in motor vehicles, comprising at least two closure elements adapted to be swivel-mounted on the tank filler neck, the at least two closure elements each having insertion bevels on a top thereof such that when a fuel nozzle is placed on the insertion bevels the at least two closure elements swivel and open the tank filler neck, wherein the at least two closure elements have projections and/or recesses that overlap each other in a closed state.
A closure device for a tank filler neck in motor vehicles, comprising at least two closure elements adapted to be swivel-mounted on the tank filler neck, the at least two closure elements having insertion bevels on a top thereof such that when a fuel nozzle is placed on the insertion bevels the closure elements swivel and open the tank filler neck, and braking devices assigned to the at least two closure elements for delayed movement during opening and closing of the tank filler neck.
A closure device, comprising spring loaded closure elements adapted to be swivel mounted on a tank filler neck, the spring loaded closure elements include tapered insertion bevels designed in such a way that, when a fuel nozzle is placed on them, the spring loaded closure elements swivel and open the tank filler neck, and a swivel axis of the spring loaded closure elements is one of oriented perpendicular to a longitudinal extension of the tank filler neck so that the spring loaded closure elements are individually mounted and close the tank filler neck in a clamshell manner.
A closure device, comprising spring loaded closure elements swivel mounted on tank filler necks, the spring loaded closure elements include tapered insertion bevels designed in such a way that, when a fuel nozzle is placed on them, the spring loaded closure elements swivel and open the tank filler neck, and braking devices assigned to the spring loaded closure elements that cause a delayed opening of the tank filler neck.
A closure device, comprising spring loaded closure elements having a top portion configured to cover an opening of a filler neck and sidewalls configured to surround an outer wall of the filler neck, the spring loaded closure elements close about the top and side of the filler neck in a clamshell manner, and swivel to open the tank filler neck when a fuel nozzle is placed on insertion bevels on a top surface thereof.
