System for inflating—deflating a tyre

A system for inflating-deflating a tyre that comprises a wheel, said system comprises a reserve of air and a valve carried on board the wheel, the air being confined to the reserve under pressure higher than that of the tyre, the valve is in communication, with the reserve and with the tyre, said valve comprises control means able to adopt:

• a resting position in which said control means ensure stable and hermetic communication between the tyre and the valve;
• an inflation position in which said control means provide communication between the tyre and the reserve, by being moved by air injected into the valve by means of an inflation electrically operated valve connected to the reserve, such that air injected into the tyre for inflating thereof being separate in flow from air injected into the valve for moving said control means;
• a deflation position in which said control means make it possible to place the tyre in communication with the exterior of the valve, by being moved by the air injected by means of a deflation electrically operated valve connected to the reserve.
