器。 In a single-cylinder hydraulic shock absorber with a reservoir chamber inside a hollow piston rod, there is a check valve D that allows free flow from the piston lower chamber to the piston upper chamber during contraction, and a check valve D that allows free flow from the piston lower chamber to the reservoir chamber during contraction. A leaf valve B that throttles to generate damping force, a check valve C that allows free flow from the reservoir chamber to the lower piston chamber during extension, and a check valve C that throttles the flow from the upper piston chamber to the lower piston chamber during extension to generate damping force. A hydraulic shock absorber characterized in that a leaf valve A for generating electricity is attached to a single valve case.
