Shock absorber for vehicle with elastic suspension - has compensator piston rendered inoperative by valve responsive to deformation velocity

摘要

The shock absorber has two elements which are deformable in the same sense as the vehicle suspension. A compensator prevents relative deformation of the elements when the relative velocity between the vehicle components to which the shock absorber is attached is below a pre-determined limits. A locking mechanism neutralises the compensator when the relative velocity is above the predetermined limit, a return mechanism ensuring that the two elements maintain a predetermined rest position. The two elements are pref. a piston and a cylinder, the latter also housing a compensator piston which a blocking valve which acts as the locking mechanism. The shock absorber may be used in a vehicle with a large load capacity and is effective over a wide load range.
