Abstract

PURPOSE:To enable automatic change of the damping property of the shock absorber corresponding to the loadage of a vehicle by enabling free setting of the damping property on the side of shrinkage at the time when the vehicle is loaded or unloaded, respectively. CONSTITUTION:The shock absorber is constituted by the 1st port 10 making the oil in a lower chamber 7 flow toward an upper chamber 6 through the intermediary of the 1st shrinkage-side damping valve 8 leading only in one direction, the 2nd port 11 provided along with the former and making the oil in the lower chamber 7 toward the upper chamber 6 through the intermediary of the valve 8 and the 2nd shrinkage-side damping valve 9, and a sleeve 12 opening or closing selectively each of the ports 10 or 11 according to the relative change in position of a piston 4. Therefore, the damping property meeting the rspective requirements under the conditions that the vehicle is loaded or unloaded can be furnished. Especially, since the rate of change of the damping force on the shrinkage side at the time when the vehicle is loaded or unloaded can be set extensively and optionally, the property on the occasion that the piston 4 operates at a low speed is improved.
