Pneumatic actuator system and method for controlling such as system

Pneumatic actuator system for a vehicle, comprising:

• at least one pneumatic actuator,
• a compressor, providing compressed air to the pneumatic actuator,
• a first intake to supply the compressor with external air, and
• a second intake connected, via a recirculation line, to an exhaust line of the pneumatic actuator and arranged to supply the compressor with air discharged from the pneumatic actuator wherein the pneumatic actuator system also includes a selecting valve which is arranged on the exhaust line of the pneumatic actuator, between the pneumatic actuator and the compressor, this selecting valve is switchable between a recirculation position, where the air flow discharged by the pneumatic actuator is directed to the recirculation line, and an exhaust position where the air flow discharged by the pneumatic actuator is directed to a low pressure circuit, depending at least on pressure of the air in the recirculation line downstream from the selecting valve or in an air tank that is arranged downstream from the selecting valve on the recirculation line and wherein air discharged from the pneumatic actuator can accumulate.
