― Pressure plate

― A/C compressor pulley

― Stator

― Snap ring

― Shim

Operation

Magnetic clutch disengagement

1. If there is no energization in the magnetic clutch stator from the A/C relay, the pressure plate cannot be engaged with the A/C compressor pulley because the magnetic clutch stator does not operate.

2. The rotation force from the drive belt is only transmitted to the A/C compressor pulley and the pulley spins.

Magnetic clutch engagement

1. If there is energization in the magnetic clutch stator from the A/C relay, the magnetic clutch stator operates and the pressure plate is engaged with the A/C compressor pulley.

2. The rotation force from the drive belt is transmitted to the compressor shaft through the pressure plate from the A/C compressor pulley.

Fail-safe

• Function not equipped.
