Volkswagen Golf Service & Repair Manual: Air conditioning system compressor with magnetic clutch
| 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). |
