ABSTRACT:
An anti-theft device for a pneumatic-tired vehicle, of the kind comprising means (4) for automatically deflating a tire (5) of the vehicle and deflating the tire (5) when the device is actuated by control means (2) and the vehicle is in motion, the deflating means (4) being moved by the centrifugal force of inertia when the corresponding wheel (3) rotates whereas they are inoperative in other cases, characterized in that the deflating means (4) comprise movable means for closing at least one orifice (7) through which air under pressure can escape from the tire (3), the movable closing means normally sealing the orifice (7) when the device is inoperative and/or the wheel (3) is stationary, whereas they unclose the orifice (7) and allow air to escape when the device is actuated and as soon as the centrifugal force of inertia reaches a sufficient value to move them.
