    • A phase change mechanism for a camshaft of an internal combustionengine comprises a drive member (14) to be connected to the camshaft drive train, a driven member (12) to be connected to the camshaft (10), a coupling element (20) interposed between, and movable relative to, the drive and driven members, and means (24, 26) connecting the coupling element (20) for rotation with the drive and driven members in such a manner that the phase of the driven member relative to the drive member is dependent upon the position of the coupling element (20). The connecting means (24, 26) is designed to permit the coupling element (20) to move between two stable end positions lying on a line generally perpendicular to the axis of rotation of the phase drive and driven members, and a reaction member (50) is connected to the coupling element (20) by a cranking means (44) which causes the coupling element (20) to move from one stable end position towards the other in response to the application of a torque acting to vary the speed of rotation of the reaction member relative to the drive and driven members.
    • 内燃机的凸轮轴的相变机构包括:与凸轮轴传动系连接的驱动部件(14),与凸轮轴(10)连接的从动部件(12);插入 并且可相对于驱动和从动构件移动,以及将联接元件(20)与驱动和从动构件连接的装置(24,26),使得从动构件相对于驱动器的相位 构件取决于联接元件(20)的位置。 连接装置(24,26)被设计成允许联接元件(20)在位于大致垂直于相驱动和被驱动构件的旋转轴的线上的两个稳定的端部位置之间移动,并且反作用构件(50) )通过启动装置(44)连接到联接元件(20),该起动装置(44)响应于施加用于改变旋转速度的扭矩而使联接元件(20)从一个稳定的端部位置朝向另一个稳定的端部位置移动 的反应构件相对于驱动和驱动构件。
