<p>The invention concerns a sphere, in particular pneumatic, comprising a rigid shell (1) and a deformable flexible membrane (2) fixed inside said shell to define two chambers whereof one at least, called pneumatic chamber (4), is destined to be filled with gas under pressure. The invention is characterised in that the sphere comprises an element (16a) whereof the mechanical properties suddenly change when the temperature reaches a predetermined value causing said element to clear a passage for the gas from the pneumatic chamber (4) through which the gas escapes, to reduce the pressure inside said pneumatic chamber. The invention is applicable to motor vehicle suspensions.</p> |
