Patent ID: 8506260

Claim:
A compressor system for use in a commercial vehicle having an engine with a turbocharger, the compressor system comprising: a compressor for supplying compressed air to the commercial vehicle; a first air feed through which air precompressed by the turbocharger is capable of being sucked-in by the compressor; a second air feed through which non-precompressed ambient air is capable of being sucked-in by the compressor; a charge-air valve device operatively arranged in the first air feed; an ambient-air valve device operatively arranged in the second air feed; and a pressure sensor operatively arranged in the first air feed, the pressure sensor determining a boost pressure provided by the turbocharger, wherein the charge-air valve device is arranged to allow sucking-in precompressed air provided by the turbo-charger only when the boost pressure provided by the turbo charger lies below an adjustable boost pressure threshold; and wherein the ambient-air valve device is arranged to allow sucking-in ambient air only when the boost pressure provided by the turbocharger overshoots said adjustable boost pressure threshold.
