The invention relates to a hydraulic buffering system which achieves balanced output of the pressure. It consists of a unidirectional fixed ratio pressure relief valve, a piston assembly a the cylinder assembly; the unidirectional fixed ratio pressure relief valve includes a valve core, a first chamber, a second chamber and a third chamber; the valve core is provided inside the second chamber stated; the first end of the valve core is connected with the first chamber; the second end of the valve core is connected with the third chamber; the second chamber is provided with a shunt channel, and a feedback oil hole is provided between the shunt channel and the third chamber; the unidirectional fixed ratio pressure relief valve is provided inside the piston; and the first chamber is connected with the rod cavity, the shunt channel of the second chamber is connected with the rodless cavity. Adopting the hydraulic buffering system achieving balanced output of the pressure stated in the invention, under the condition of not changing the structure of the original hydraulic buffer, the equal output pressure of the hydraulic buffer can be achieved by providing the unidirectional fixed ratio pressure relief valve inside the piston, the mechanical performance is stable with a simple structure, which is easy for implementation, maintenance and replacement.
