The compressor is the driving element of the cold A/C loop and is also the most complex in terms of its technology features. Valeo, thanks to its expertise, has developed a full range of new compressors with different technologies to meet most of the customers’ expectations.


A compressor is designed according to two main technologies: the piston type or the rotary type. The Piston type is the most common. Inside the piston type, you may find swash plate technology and wobble plate technology. In terms of the rotary type, the two main technologies are vane technology and scroll technology.


Valeo compressor technologies have been given three names: DKV, DKS and DCS. Each Valeo compressor is tested in compliance with the O.E. process: leakage, durability, noise, vibration etc. With our wide-reaching offer you will find the compressor you need at Valeo. Thanks to its O.E. expertise and innovations in terms of technological features, Valeo is able to meet the vehicle’s requirements. Valeo compressors are optimized and designed with a perfect finish and selection of all components, particularly on the valves, bearings, pistons, swash plate and clutch, for high reliability and an enhanced performance. Valeo strives to reduce the level of noise and vibrations for driver comfort. The compressor must be replaced after a crash, breakdown or leak. When replacing the compressor, you must check and flush the A/C loop, and change the receiver drier and the expansion valve.
