Apparatus for the automatic filling of motor vehicle tires

摘要

A tire-filling system has an electronic control unit response to the tire pressure and the vehicle operating conditions for automatically operating pneumatic tire-filling valves to increase or reduce the tire pressure to setpoint values determined by the electronic control unit and matching the driving conditions. The pressure is delivered from a variable volume source in which a control element increases or decreases the volume. The system can be operated as an open system or a closed system.
