A/C Compressor Regulator Valve

A/C Refrigerant System Component Description

A/C Compressor Regulator Valve





On A/C compressors without A/C Clutch (N25), the A/C Compressor Regulator Valve (N280) is integrated with the A/C compressor. Its function is controlled by the Motronic Engine Control Module (ECM) (J220) in accordance with engine loads, speed and engine coolant temperature. The valve regulates the low pressure (suction) side of the A/C compressor, thus controlling the evaporator temperature.
