1- Product description - Lubrication
The gear pump situated at the end of the drive shaft draws oil from the oil reservoir and lubricates the parts
of the compressor.
Oil flow
When the compressors start operating, the gear pump draws oil from the reservoir and pumps it through
an oil passage in the shaft.
The oil then flows through ports in the shaft to lubricate the bearings and the shaft seal.
The area between the swash plate and the shoes is lubricated by the splashing action of the oil flowing
through the thrust bearings. The compressor remains constantly lubricated thanks to the oil circulating
together withthe refrigerant.
Valeo compressor innovative internal design ensures that almost no oil remains mixed with the refrigerant
that is flushed into the air conditioning system.
Refrigerant itself plays a lubricant role to prevent the compressor to be damaged in case of oil shortage.
