Abstract

A sealing device is suitable, for example, for conducting verification and testing of fluid-tightness, and includes a body supporting an end piece equipped with a gasket. The gasket presents an outer surface in which at least one area is in the form of a truncated cone. A sealing method concerns the sealing of an aircraft pipe presenting an opening arranged behind a wall, with the aid of a sealing device as described above.

First claim

The invention claimed is:

1. A sealing device for sealing a pipe of an aircraft, the sealing device comprising:
a body having a plurality of non-interconnected notches on an outer surface thereof;
an end piece supported by said body and equipped with a gasket comprising an outer surface in which at least one area is in the shape of a truncated cone, the end piece being mobile relative to the body;
a member acting selectively one at a time on individual ones of said plurality of non-interconnected notches and having structure to enable the member to be attached to a protective support of the aircraft to secure said body in place relative to the pipe of the aircraft; and
an elastic element acting on the end piece in a direction that tends to move the end piece away from the body.

2. The sealing device according to claim 1 , wherein the end piece forms a distal end of a stem, wherein said stem has a cylindrical head at its proximal end, opposite its distal end, and wherein the body comprises at least one tubular area and a shoulder at one of its ends arranged so that said cylindrical head can slide inside this tubular area until the shoulder is reached.

3. The sealing device according to claim 2 , wherein the elastic element comprises a spring housed inside the tubular area and which applies force to the cylindrical head in the direction of the shoulder.

4. The sealing device according to claims 2 , wherein the end of the body opposite the shoulder is closed off by a stopper.

5. The sealing according to claim 1 , wherein the body presents an outer surface comprising a gripping area.

6. The sealing according to claim 1 , wherein the gasket is made of rubber.

7. The sealing according to claim 1 , wherein the truncated-cone shape is such that its smallest diameter is less than 9 mm and its largest diameter is greater than 13 mm.
