Beschreibung
Zusammenfassung:	An automotive air conditioning compressor assembly that includes a compressor (12) capable of exhibiting an over-torque condition, an electromagnetic clutch (14), and an over-torque protection device located between the compressor and the accessory drive. The over-torque protection device is configured to decouple the compressor and the accessory drive when the over-torque condition occurs. The over-torque protection device uses a frangible part (30) that breaks when an over-torque condition occurs and parts equipped with helical ramps (28) to force the rotor (22) and stator of the clutch apart to disengage the compressor from the vehicle accessory drive.
