  • Patent number: 10738802
    Abstract: A hydraulic buffer pertains to the field of hydraulic parts. A signal device (X) is installed at a position close to an end of a cylinder stroke to control movement of slide valves (12, 18, 12a, 12b, 12c, 12d, 12e, 12f, F1, F2, F3, F4) of the hydraulic buffer, to dynamically adjust the degree of valve openness and a liquid flow direction of a buffering module (Y), and therefore control pressure of oil entering an oil returning chamber of a cylinder. The high-pressure chamber of the cylinder releases pressure and unloads, and/or the oil returning chamber throttles to load pressure, such that a moving speed of a cylinder piston (6) at the end of the stroke is controlled, realizing buffering of the cylinder.
