Abstract
The utility model discloses a shock absorber valve system with a maximum recovery speed control function. The shock absorber valve system comprises a working cylinder and a piston rod, wherein the piston rod is movably arranged in the working cylinder; an upper piston and a lower piston are arranged on the piston rod in parallel; when the recovery speed of a shock absorber reaches a set extreme value, a sliding seat pushes an inner ring of a flow control valve to move forward until the flow control valve is bent and tightly attached to the step end face of the lower piston, so that the flow control valve closes a shock absorption oil flowing channel, and the damping force is increased; the recovery motion of the shock absorber slows down, shock absorption oil flow is reduced, and the damping force is reduced; then the recovery speed of the shock absorber is increased; and the speed is adjusted automatically, so that the shock absorber can get a constant recovery speed and a constant recovery damping force. The shock absorber valve system is provided with the upper piston and the lower piston as well as two piston rings; and due to the correlation of a recovery valve and the flow control valve, the flow of the shock absorber during recovery is controlled, so that the maximum recovery speed of the shock absorber can be controlled.
