Volkswagen Golf Service & Repair Manual: Air conditioner compressor without magnetic clutch

The air conditioner compressor is driven by a V-belt from the engine.
A shear link is incorporated in the air conditioner compressor V-belt pulley. In the event of stiffness in the air conditioner compressor, it shears off and protects the V-belt drive from overload.
The air conditioner compressor draws refrigerant gas from the evaporator, compresses it and sends it to the condenser.
  Note
The air conditioner compressor contains refrigerant oil, which is miscible with R134a refrigerant at all temperatures.
The maker's nameplate states the refrigerant for which the air conditioner compressor is suitable. A valve regulates the pressure on the low-pressure side within the specified range (regulation characteristic).
The regulating valve for this air conditioner compressor is externally activated.
The engine should be started only when the refrigerant circuit has been fully assembled → Chapter.
The air conditioner compressor has an internal oil circuit to ensure that the air conditioner compressor is not damaged when the refrigerant circuit is empty. This means that about 40 to 50 cm3 refrigerant oil remain in the air conditioner compressor.
