<p>A hydraulic vibration damper featuring reduced noise characteristics wherein a first and a second damping valve system operate in response to fluid pressure to control flow of damping fluid in each direction of movement, respectively, of a piston of the damper. The first and second damping valve systems include a preliminary throttling aperture, an aperture disc defining a preliminary aperture located downstream relative to the direction of fluid flow through the respective damping valve systems, and a noise reduction mechanism for producing a post-throttling effect downstream of the preliminary aperture, the noise reduction mechanism being formed by a baffle plate located to be impinged by fluid flowing through the preliminary aperture, the baffle plate being arranged to define a quieting duct immediately adjacent the baffle plate upstream thereof.</p> |
