4. FUNCTION DESCRIPTION
1) Compressor
All compressor are belt-driven from the engine crankshaft through the compressor clutch pulley.
The compressor pulley rotates without driving the compressor shaft until an electromagnetic
clutch coil is energized. When voltage is applied to energize the clutch coil, the clutch plate and
hub assembly is drawn rearward toward the pulley. The magnetic force locks the clutch plate
and pulley together as one unit to drive the compressor shaft. As the compressor shaft driven, it
compresses the low pressure refrigerant vapor from evaporator into high pressure, high
temperature vapor. The refrigerant oil that is used to lubricate the compressor is carried with
the refrigerant.
2) Magnetic Clutch
The magnetic clutch is assembled in front of the compressor and controls to stop or operate the
compressor. The center piece is inserted to the compressor crankshaft and rotate the only the
pulley when it doesn't operate the compressor. When the A/C switch is turned ON, the current
flows into the wrapped coil of the stator and the stator is converted to the powerful
electromagnet. Therefore, the compressor can rotate with the pulley together because the
stator can pull the center piece tightly.
3) V-5 Compressor-General
Vehicle using the V5 compressor may have differences between installations in the mounting
brackets, the drive system, the pulleys, the connections and the system capacities. Basic
overhaul procedures are similar between the compressors used on different vehicles. When
serving the compressor, keep dirt and foreign material from getting on or into the compressor
parts and the system. Clean tools and a clean work area are important for proper service. The
compressor connections and outside of the compressor should be cleaned before performance
of any on-vehicle repairs and before removal of the compressor. The parts must be kept clean
at all times and any parts that are to be reassembled should be cleaned with trichloroethane,
naphtha, stoddard solvent, kerosene or equivalent solvents and dried with dry air. Use only
lintfree cloths to wipe the parts. The operations described are based on bench overhaul with the
compressor removed from the vehicle, except as noted. They have been prepared in the order
of accessibility of the components. When a compressor is removed
servicing, the amount of oil remaining the compressor should be drained, measured and
recorded. This should then be discarded and new polyalkaline glycol (PAG) refrigerant oil
added to the compressor.
