The next generation of variable displacement piston compressor technology, Delphi\'s Compact Variable Compressors (CVC), are based on a swash plate simple harmonic motion mechanism. The enhanced mechanism performance makes the CVC adaptable to both pneumatic and electronic control.Delphi\'s CVC is adaptable to a full range of vehicles. While our current product portfolio includes CVC ranging from 100 cc displacement to 185 cc displacement, Delphi can design and validate a CVC for a specific application. The CVC can be applied to both thermostatic expansion valve and orifice tube systems.
