## Abstract

Plug system built into the top of a fuel tank filler pipe, comprising a plug with a locking device, a fuel flap able to occupy a position allowing access to the pipe and a position preventing access to the pipe, and a mechanical connection system able to transmit a movement from the flap to the locking device in such a way as to lock or unlock the plug. The mechanical connection system comprises components able to interact by part of a movement of one component being transmitted to another, adjacent component in such a way that only part of the movement of the flap can be transmitted to the locking device in order to lock or unlock the plug.

## Claims

### Claim 1

A plug system built into the top of a fuel tank filler pipe, comprising
a plug (1) with a locking device,
a fuel flap (9) able to occupy a position allowing access to the pipe and a position preventing access to the pipe, and
a mechanical connection system able to transmit a movement from the flap (9) to the locking device in such a way as to lock or unlock the plug (1),
wherein the mechanical connection system comprises components able to interact by part of a movement of one component being transmitted to another, adjacent component in such a way that only part of the movement of the flap (9) is able to be transmitted to the locking device in order to lock or unlock the plug (1).

### Claim 2 (depends on 1)

The plug system according to claim 1, wherein the plug (1) is retractable under the action of a force directed against it along an axis essentially parallel to the axis of the pipe.

### Claim 3 (depends on 1)

The plug system according to claim 1, wherein the plug (1) comprises a device for regulating the pressure in the filler pipe.

### Claim 4 (depends on 1)

The plug system according to claim 1, wherein the locking device comprises a ring (3) attached to the plug (1) in a bayonet system.

### Claim 5 (depends on 1)

The plug system according to claim 1, wherein the mechanical connection system comprises at least a link (7) and a cam (6) able to cooperate in a mechanical connection that can is able to be deactivated for at least part of the movement of the flap (9).

### Claim 6 (depends on 1)

The plug system according to claim 1, wherein the mechanical connection system comprises at least two components able to interact by means of complementary gears.

### Claim 7 (depends on 1)

The plug system according to claim 1, wherein the fuel flap (9) comprises a door able to pivot about an axis (8) essentially perpendicular to the axis of the pipe.

### Claim 8 (depends on 7)

The plug system according to claim 7, wherein the door is able to pivot in the course of a movement comprising
a first part where the mechanical connection system is deactivated,
a second part where the locking device is moved from a locked position to an unlocked position or vice versa, and
a third part where the mechanical connection system is also deactivated.

### Claim 9 (depends on 8)

The plug system according to claim 8, wherein
the first part of the pivoting corresponds to an angular variation of between 0° and 15°,
the second part of the pivoting corresponds to an angular variation of between 10° and 65°, and
the third part of the pivoting corresponds to an angular variation of between 60° and 90°.

### Claim 10 (depends on 1)

The plug system according to claim 1, comprising a protective shield (19) for the plug (1).
