This effectively reduces fluid noise and improves throttling efficiency.

The application discloses a buffer device of a linear reciprocating motion type hydraulic cylinder, and mainly comprises a one-way valve assembly, a hydraulic cylinder moving part, a cylinder sleeve and a piston cavity. The free moving sealing body in the one-way valve assembly is used as a control element to control the opening and closing of the one-way valve hydraulic fluid passage, so that the hydraulic flow area of the buffer device is variable, the impact on the hydraulic cylinder moving part at the motion end point is reduced, and the hydraulic cylinder moving part can reach the end point position in time. The opening and closing time of the one-way valve hydraulic fluid passage can be variable according to the moving speed of the hydraulic cylinder moving part and the flow rate of the fluid, and the structure is simple, so that the buffer demand of the hydraulic cylinder moving part under variable working conditions can be met. The application solves the mutual contradiction between the hydraulic cylinder stop lag and the hydraulic cylinder impact in the prior art, and has important significance for improving the safety of the reciprocating motion type hydraulic cylinder.
