Abstract

The shock absorber has a base with a central reservoir cntg. hydraulic fluid. The fluid container has a central column (13) with a central (11) to receive a needle valve (8). The outside of the column is fitted with a cone (6) made from elastic material. The top of the absorber has a cover plate (2) over a cylinder (14) in the base. The needle valve is fixed to the underside of the plate and the outside of the cone is fixed to the inside of the inner cylinder.
