Method and device for controlling regulation, drying and regeneration of a regulator dryer unit in a pneumatic-hydraulic braking system of a vehicle

This invention relates to an electro-pneumatic control system that regulates the loading, regeneration and off-load phases according to the vehicle's operating conditions. The system comprises a pressure regulator-air dryer (3) with two solenoid valves for discharging (3a) and regeneration (3b), a diverter valve (4) to enable the separate filling of the pneumatic suspension circuit and a control module (6) and any other valves to divert compressed air to other independent circuits (fig. 1).
