Abstract

This pressure sensor (8) is intended to be placed in a tire mounted on a rim (2) equipped with a valve (6) allowing air to be let into and removed from the tire.

It comprises a support (22) fixed at the level of the valve (6) by a screw or the like.

The support (22) comprises a wall (30) for bearing on the valve (6), this wall (30) being elastically articulated to the rest of the support (22).

Claims

1. A pressure sensor (8) intended to be placed in a tire mounted on a rim (2) equipped with a valve (6) allowing air to be put into and let out of the tire, the sensor (8) comprising a support (22) fixed at the level of the valve (6), characterized in that the support (22) comprises a wall (30) for bearing on the valve (6), this wall (30) being elastically articulated to the rest of the support (22).

2. The pressure sensor as claimed in claim 1, characterized in that the support (22) is made of synthetic material and in that the bearing wall (30) forms just one piece with the support (22).

3. The pressure sensor as claimed in claim 2, characterized in that the elastic articulation (32) between the bearing wall (30) and the rest of the support is produced by thinning the material, giving it elasticity.

4. The pressure sensor as claimed in one of claims 1 to 3, characterized in that the edge of the bearing wall (30) opposite the elastic articulation (32) is connected to the rest of the support by a bellows (26).

5. The pressure sensor as claimed in claim 4, characterized in that the space defined by the bearing wall (30), the bellows (26) and the rest of the support is closed at both ends.

6. The pressure sensor as claimed in one of claims 1 to 5, characterized in that its support (22) further comprises a lip (34) placed on the opposite side to the bearing wall (30) and intended to come into contact with the rim (2) when the sensor (8) is in the mounted position.

7. The pressure sensor as claimed in claim 6, characterized in that the lip (34) forms just one piece with the support (22).
