Variable Displacement Type Compressors

The variable displacement compressors are used for the internal combustion engine vehicle application.
The compressor technology  can reduce engine loads thanks to its flexible refrigerant discharge capacity.
Sanden variable compressors contribute to lower fuel consumption, CO2 emission reduction and drivers' comfort.

Swash Plate Type
(PX series)

The compression system that uses swash plates to convert rotational motion into reciprocating piston motion is used for PX series compressors.
Because of its excellent durability at high engine speeds, many customers use the compressors with this compression system.

  • PXC
    PXC

    PXC is a swash plate type variable displacement compressor with clutch assembly for power transmission, which is adaptable to a wide range of vehicle needs.
    The discharge capacity (amount of compression) is controlled by changing the swash plate angle in response to electrical signals from the vehicle.

    Specifications
    Discharge capacity 140cc 170cc
  • PXE
    PXE

    PXE is a swash plate type variable displacement compressor without clutch assembly for power transmission.
    Weight reduction became possible because there was no need to cut off the power from engine to compressor.
    The discharge capacity (amount of compression) is controlled by changing the swash plate angle in response to electrical signals from the vehicle.

    Specifications
    Discharge capacity 140cc 170cc

Wobble Plate Type
(SDV/C series)

The compression system that uses an wobble plate to convert rotational motion into reciprocating piston motion is used for SDV/C series compressors.
The compressors using this compression system can withstand a long period of operation in severe usage environment.

  • SDV
    SDV

    SDV is an internal variable displacement compressor of which discharge capacity is controlled by detecting the refrigerant pressure in the air conditioning system with a sensor installed in a compressor.

    Specifications
    Discharge capacity 100cc 125cc 160cc
  • SDC
    SDC

    SDC is an external variable displacement compressor of which discharge capacity is controlled in response to electric signals which are generated by the vehicle according to the refrigerant pressure condition which is also detected by the vehicle.

    Specifications
    Discharge capacity 125cc 160cc

    • [Refrigerant discharge capacity]
    The larger the refrigerant discharge capacity, the larger the cabin space that can be cooled.
