AbstractThe deflating device, in particular intended for rapid intervention or military vehicles, comprises a servovalve (18) having a large-section passage instantaneously putting the interior of the tire in communication with the open air, a pressure sensor (21) with an associated circuit (22,23,24) an electrovalve (17) and its associated circuit being supplied with a chopped or otherwise interrupted current through a rotating transformer (12,14), the sensor circuit being such that, when the predetermined low pressure value is reached, it causes the closure of the servovalve (18) by the electrovalve (17).
