Compressor Clutch: Description and Operation

MAGNET CLUTCH




The magnet clutch serve to transmit engine power to the compressor unit. It is built into the compressor shaft. When current flow through the magnet clutch coil, the drive plate is attracted so that the pulley and compressor shaft rotate as a unit. When the compressor is not in use, the pulley alone rotates freely.

Compressor Clutch "ON" Delay System




When air conditioning system relay operates, a signal is entered into engine control module. Engine control module then judges engine operation and activates A/C relay. Maximum clutch "ON" delay occurs 0.8 seconds after A/C relay activates.
