Abstract
An automatic tire-filling apparatus for a motor vehicle has an electronic controller which, in response to sensors for the operating state of the vehicle, controls pneumatic valves for the tires and a compressor to enable the tire pressure to be matched to such conditions as travel speed, vehicle load, roadway conditions and terrain. The compressor is in a normal operating state part of a closed system with the tire and the pressure reservoir and is directly connected to the pressure reservoir without the intermediary of a switching element.
