The utility model relates to the technical field of cushion valves, and discloses a cushion valve body mechanism which comprises a valve body, a channel connector is arranged on one side of the valve body, a valve hole allowing a spring to be embedded is formed in the side, adjacent to the channel connector, of the valve body, one end of the spring abuts against a steel ball, and one end of the channel connector 0 is communicated with a first channel and a third channel. Through cooperation of the valve body, the first channel, the second channel, the third channel, the spring and the steel ball, when the flow direction of the channel connector flows into the valve body, the one-way valve steel ball is opened, quick starting is not controlled by the buffering valve needle, back pressure is generated in a cylinder cavity only during backflow, closing of the one-way valve steel ball is controlled by the valve needle, and the buffering purpose is achieved through the third channel; the two groups of valves are c
