Volkswagen Golf Service & Repair Manual: Air conditioner compressor without magnetic clutch, with elastic drive
coupling
| The air conditioner compressor is driven directly by the
power steering vane pump. |
| There is an overload protection on the drive shaft of the
air conditioner compressor, which shears in the event of the air
conditioner compressor seizing, thus permitting the power
steering vane pump to remain operational. |
| 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. |
