A/C Compressors Take A Pounding

The A/C compressor is a pump that compresses and circulates refrigerant within the A/C system. Some have pistons inside while others have rotating vanes on an eccentric or a pair of metal scrolls or spirals around an eccentric. Many late-model vehicles have “variable displacement” compressors that change the piston stroke to increase or decrease the volume of refrigerant flowing through the system. Some of these run continuously instead of cycling on and off like conventional A/C compressors.
