    • A vehicle suspension damper (1410) comprising:
      a damping chamber (35) containing a damping fluid, and a piston and a piston rod moveable in the damping cylinder;
      a valve (1500) for controlling movement of said damping fluid in compression and/or rebound of said vehicle suspension damper, the valve having:
      a primary valve member (1540) for resisting damping fluid flow along a first fluid flow path from a first side of the valve (1500) to a second side of the valve;
      a first pressure reducing means (1515) and a second pressure reducing means (1510) in a second fluid flow path between said first and second sides of the valve;
      wherein a surface (1580) of the primary valve member is exposed to damping fluid in said second fluid flow path between said first and second pressure reducing means;
      the arrangement being such that, in use, during compression and/or rebound of said vehicle suspension damper damping fluid is urged to flow through said first fluid flow path at a first fluid pressure resisted by said primary valve member (1540), and at the same time pressure of damping fluid in the second fluid flow path is reduced by the first and second pressure reducing means to a second fluid pressure lower than said first fluid pressure; and
      the second fluid pressure acts on a said surface (1580) of said primary valve member (1540) so that the primary valve member increases its resistance to damping fluid flow along said first fluid flow path.
    • 一种车辆悬架阻尼器(1410),包括:阻尼室(35),其包含阻尼流体;以及活塞和活塞杆,其可在所述阻尼缸中移动; 用于控制所述阻尼流体在所述车辆悬架阻尼器的压缩和/或反弹中的运动的阀门(1500),所述阀门具有:主阀构件(1540),用于抵抗来自第一侧面的第一流体流动路径的阻尼流体流动 的阀(1500)的第二侧; 在阀的第一和第二侧之间的第二流体流动路径中的第一减压装置(1515)和第二减压装置(1510) 其中所述主阀构件的表面(1580)暴露于所述第一和第二减压装置之间的所述第二流体流路中的阻尼流体; 该布置使得在使用中,在所述车辆悬架阻尼器阻尼流体的压缩和/或回弹期间被迫在所述主阀构件(1540)抵抗的第一流体压力下流过所述第一流体流动路径,并且在 第二流体流动路径中的阻尼流体的相同时间压力被第一和第二减压装置减小到低于所述第一流体压力的第二流体压力; 并且第二流体压力作用在所述主阀构件(1540)的所述表面(1580)上,使得主阀构件增加其沿着所述第一流体流动路径的阻尼流体流动的阻力。
