ABSTRACT:
The characteristics of a double-tube shock absrober are variable in response to temperature variations as a result of viscosity variations of the damping liquid. In view of compensating for such variations of the damping characteristics the central cavity is connected with the annular compensation chamber by a throttled flow cross-sectional area. This throttled flow cross-sectional area is variable in response to ambient temperature. In view of varying the flow cross-sectional area a control bar is provided on the outer surface of the cylinder of the shock absorber. This control bar extends substantially in axial direction of the shock absorber and is fixed to the cylinder at a location remote from the location of the throttled flow cross-sectional area. The other end of the control bar cooperates with the flow cross-sectional area and effects the variation thereof.
