Abstract
A hydraulic damper includes an internal accumulator for storing and dissipating energy resulting from a fluid pressure spike inside the damper. A housing is mounted on a piston rod above a reciprocable piston. A compressible medium is stored in the housing. A valve assembly controls the flow of fluid into and out of the accumulator. When a sudden fluid pressure rise occurs, the medium compresses to store the energy. When the pressure rise dissipates, fluid exits the accumulator as the medium expands.
