V-6 Variable Displacement Compressor: Description: General
WARNING: This page is about a different car, the 2004 Infiniti Q45. However, it is still accessible from the selected car via links, so may be relevant.
The variable compressor is basically a swash plate type that changes piston stroke in response to the required cooling capacity.
The tilt of the wobble (swash) plate allows the piston's stroke to change so that refrigerant discharge can be continuously changed from 14.5 to 184 cm3 (0.885 to 11.228 cu in).
