Abstract

This pressure detector (8) is adapted to be disposed in a tire mounted on a wheel rim (2) provided with a valve (6) permitting the introduction of air into and the withdrawal of air from the tire. This detector (8) is fixed to the valve (6). It comprises, spaced from the point of securement to the valve, a deformable lip (32) creating a substantially continuous bearing zone against the wheel rim (2).

Claims

1. Pressure detector (8) adapted to be disposed in a tire mounted on a wheel rim (2) provided with a valve (6) permitting the introduction and withdrawal of air into and from the tire, the detector (8) being secured to the valve (6),

characterized in that the detector (8) comprises, spaced from the point of securement to the valve, a deformable lip (32, 32′

) adapted to form a substantially continuous bearing zone against the wheel rim (2).

2. Pressure detector according to claim 1, characterized in that it comprises a support of synthetic material and in that the lip (32, 32′

) is formed of one piece with the support.

3. Pressure detector according to claim 2, characterized in that the lip (32, 32′

) is made by thinning of material which gives it flexibility.

4. Pressure detector according to one of claims 1 to 3, characterized in that the detector (8) has a substantially parallelepipedal shape and in that the deformable lip (32, 32′

) is provided along the substantially rectilinear edge of the detector.

5. Pressure detector according to one of claims 1 to 4, characterized in that the deformable lip (32, 32′

) is located opposite the point of securement of the detector (8) to the valve (6).

6. Pressure detector according to claim 1, characterized in that the deformable lip (32′

) is constituted by a plurality of teeth (33) adapted to create a substantially continuous bearing zone against the wheel rim (2), after flattening.

7. Pressure detector according to claim 6, characterized in that the teeth (33) are made of a rigid plastic material.
