VEHICLE TYRE PRESSURE CONTROL SYSTEM

The present invention relates to a vehicle tyre pressure control system, comprising means for controlling and supplying pressure and deflation limiting valves that are in correspondence with each tyre of a vehicle; wherein the means for controlling and supplying pressure is in communication with each tyre, and is also enabled to supply them with a preset inflation pressure; each limiting valve being in turn inserted and installed between the control means and the same tyres; wherein the same limiting valve is enabled to exhibit a conditioned non-return capability, and is also enabled to exhibit a conditioned bi-directional capability, said non-return capability and said bi-directional capability being conditioned according to a differential with the preset inflation pressure supplied from the control means.
