A rotary vibration damper comprises one or more vanes secured to a rotor within a housing filled with damper fluid, the vane or vanes cooperating with one or more fixed walls to define complementary fluid-filled chambers within the housing between which fluid will flow as relative vibratory movement occurs between the housing and the vane or vanes. A partition wall movable axially within the housing like a piston is spaced from one end of the vane or vanes to define a restricted path for the flow of damper fluid between complementary chambers. The restriction of the flow path, and hence the vibration damping effect, can be increased or decreased by axial movement of the partition wall. |
