Vane type phaser system deflected the blade through the internal hydraulic pressure to achieve stepless adjustment of the phase angle,phase adjustment range and response speed of a very substantial improvement.In addition, the structure of the program vane type phaser compact system, whether it is the recent camshaft or the exhaust camshaft can easily be arranged.Vanes are the main part of the camshaft phaser, Their quality is also crucial.
