1. be used for the device that internal combustion (IC) engine camshaft changes for the drive wheel relative rotation, has a built-in fitting (2) that is connected with the antitorque commentaries on classics of camshaft (1), these parts have galianconism or the fin (4a to 4d) that radially extends at least, this device also has a driven cell rotor (5), this cell rotor has a plurality of being distributed on the circumference, the cell that defines by the galianconism (6a to 6d) on the cell rotor, galianconism or fin that cell is positioned at the built-in fitting of angular movement wherein are divided into two (7a to 7d of pressure chamber, 8a to 8d), when its supercharging or release, can between two final positions, rotate by galianconism or fin camshaft with respect to cell rotor, the pivotal position changes the damping mechanism (21,22 by combination near the final position time;

  • 25,26;

         32) by hydraulic damping, it is characterized by, damping mechanism is provided with throttle chink (32), and throttle chink (32) is formed on a depression (21 on one of built-in fitting galianconism or cell rotor galianconism,

         22) and be correspondingly positioned between the projection (25,26) on cell rotor or the corresponding adjacent galianconism of built-in fitting.
