The air conditioner compressor is driven by a V-belt from the engine.

An electromagnetic clutch is fitted to the air conditioner compressor. When the air conditioning system is switched on, it transmits the mechanical drive between the V-belt pulley and the air conditioner compressor drive shaft. A fusible link is incorporated in the air conditioner compressor V-belt pulley. In the event of stiffness in the air conditioner compressor, it trips the electromagnetic clutch 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 can be mixed with R134a refrigerant at any temperature. 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). So that the air conditioner compressor suffers no damage when the refrigerant circuit is empty, the magnetic clutch is disconnected and the regulating valve for the air conditioner compressor -N280- is no longer activated (the air conditioner compressor idles with the engine).
