With the new clutch for auxiliary assemblies, the compressor is completely separated from the engine by opening the clutch when the cut-out pressure is reached. The unit comprises a plneumatically actuated cylinder and the clutch itself, consisting of a lamella set with three discs. Since the clutch is flooded with engine oil during operation, there is pratically no wear.
The multi-disc clutch ensures a reduction in fuel consumption by engaging and disenganging the compressor to meet demand, thus also reducing CO2 emissions. The normally closed design of the clutch ensures that, in the event of a control malfunction, for example, the compressor continues to run and maintains the supply of compressed air.
