Abstract
The invention discloses a valve system of a shock absorber with a maximum resume speed control function. The valve system of the shock absorber with the maximum resume speed control function comprises a work cylinder and a piston rod. The piston rod is moveably arranged in the work cylinder. The piston rod is provided with an upper piston and a lower piston in parallel. When the resume speed of the shock absorber reaches a limit value set, a sliding base pushes an inner ring of a flow control valve piece to move forward till the flow control valve piece is bended and attached to the step end face of the lower piston so that the flow control valve piece closes a flow channel of the shock absorber, therefore, the damping force is increased, the resume movement of the shock absorber is slowed down, the flow of the shock absorbing oil is reduced, and the damping fore is decreased. While the resume speed of the shock absorber is increased again, and the resume speed can be automatically adjusted, so that the shock absorber obtains a constant resume speed and a resume damping force. According to the valve system of the shock absorber with the maximum resume speed control function provided by the invention, the upper and lower pistons and two piston rings are arranged, and the flow in the resume process of the shock absorber is controlled through associated effect of a resume valve piece and the flow control valve piece, therefore, the maximum resume speed of the shock absorber is controlled.
