AI Technical Summary

Problems solved by technology

However, due to the tilting of the protective cap when it is opened by the feed nipple, dirt can fall and be carried into the filler pipe during the tilting of said closure and eventually into the fuel tank
Furthermore, the inclination of the cover plate requires a space specially provided for this purpose, thus increasing the overall size of the system

Embodiment Construction

[0047] Figures 1 to 7 : Variation A1

[0048] The systems shown in these figures include:

[0049] a closing flap (1) and a control flap (2) carrying a protective flap (10), the movement of which controls the flap causing the closing flap (1) to move;

[0050] a body (3) provided with an axis (4) around which said covers (1, 2) are movable, and said body provided with helical grooves (5) for guiding said covers the movement of the plate (1, 2);

[0051] a seal (6) arranged between the closing cover (1) and the body (3);

[0052] A spring (7), which is compressed by the covers (1, 2) in the locked position and transmits a helical upward (during unlocking) or downward (during locking) movement to all The cover plate (1, 2);

[0053] A cover (8) which includes a hole (9) for cleaning the filling tube (not shown) when the system is in the open position, and which is compatible with the corresponding hole (9') alignment;

[0054] A dust seal (11) for the shield.

Abstract

A system for locking a closure mechanism for a fuel-tank filler pipe covered by a fuel flap, the closure mechanism includes a shutter allowing automatic opening of the pipe via action of a fuel-dispensing nozzle, this shutter being retractable through action of thrust directed against it along an axis parallel to the axis of the pipe head and integral with a return spring allowing it to be held in the closed position. The system includes a lever integral with the closure mechanism and having the effect of locking / unlocking it, depending on its position, and a lever arm, integral with the fuel flap, that can act effectively on the lever only to lock the mechanism when it is unlocked and the fuel flap is being closed.

Description

technical field [0001] The invention relates to a closure system for a fuel tank fill pipe. Background technique [0002] The filler pipe of a fuel tank, especially a fuel tank mounted on a motor vehicle, is closed during normal use other than during tank filling. Closing is usually carried out by means of a cap which is inserted into the upper part of the tube while causing a rotational movement of the cap in order to close the tube in a liquid-tight and gas-tight manner. There are various types of caps, such as those made of metal and / or plastic, that pinch a seal to seal by twisting it, or that are inserted in the center of the outer part of the fuel pipe by turning Sealed with a key. [0003] The cap is usually removed manually by the user or service station personnel before filling the tank and after filling it is replaced and the tube closed. When the fuel tank is filled, the cap may sometimes be forgotten and not replaced, resulting in the cap being lost and leavin...
