The invention relates to a shock absorption piston valve. The shock absorption piston valve comprises a first fixing ring provided with a first oil hole, a first gasket, an upper elastic valve block provided with a second oil hole communicated with the first oil hole, a shock absorption piston, a lower elastic valve block, a second gasket, a second fixing ring and a piston sealing ring, wherein the upper elastic valve block is pressed on the top of the shock absorption piston, the top of the shock absorption piston is provided with a first oil groove communicated with the second oil hole and asecond oil groove movably sealed by the upper elastic valve block, the bottom of the first oil groove is provided with a third oil hole, the bottom of the second oil groove is provided with a fourthoil hole, the bottom of the shock absorption piston is provided with a third oil groove communicated with the third oil hole, the lower elastic valve block is provided with a fifth oil hole communicated with the third oil groove, is pressed on the bottom of the shock absorption piston, and movably seals the third oil groove, the second fixing ring is located below the second gasket, and the pistonsealing ring is fixed to the shock absorption piston. The shock absorption piston valve is simple in structure, good in shock absorption effect and stable in shock absorption.
