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.

Benefits

• Compact design, better packaging, and lower mass
• Lower mass enhances fuel economy improvement
• Smaller diameter, shorter length for easier installation
• Die-cast aluminum shell for a lightweight, high strength compressor
• Variable displacement design provides:
  
• Smooth, continuous operation
• Improved operator comfort
• Improved fuel economy
• Improved dehumidification
• Integrated control valve enables compact packaging
• Electronic control system capability enhances system performance and improves cool-down
• Compact clutch arrangements provide design flexibility
• Best in class NVH (noise, vibration, handling) characteristics for quiet operation and customer satisfaction
• High speed capability for uninterrupted air conditioning at high engine speeds
• Options available include:
• Clutchless or with clutch
• Electronic control valve or pneumatic control value
• Discharge shut-off valve 
• Suction shut-off valve
• Thermal fuse or thermal switch
• High pressure relief valve for safety
• Flexible pulley configuration options
• Various vehicle engine and refrigeration interface options
  

Typical Applications

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.
