    摘要： A shock absorber includes an expansion-side passage and a contraction-side passage arranged alternately side by side along a circumferential direction, seats provided to surround an outlet port of the expansion-side passage or an outlet port of the contraction-side passage, and valve bodies. The seats has an arc-shaped outer seat portion, middle seat portions extending from respective both ends in a circumferential direction of the outer seat portion toward a center axis side of the piston, and an inner seat portion extending from center axis side ends of the middle seat portions oppositely to the outer seat portion side in a circumferential direction to connect the neighboring middle seat portions. The inner seat portion is placed on a straight line that connects the center axis side ends of the middle seat portions.

    摘要： A vehicle shock absorber generates an additional counter-force acting counter to the direction of movement near the limit position of movement. The shock absorber substantially comprises a damping medium-filled damping cylinder that is divided into two damping chambers by a main piston. The main piston is axially moveable relative to the damping cylinder and is attached to a piston rod. A second piston/damping piston that contains one or more first and second through-ducts is mounted to the piston rod. The ducts are defined by first and second flow-limiting devices such as multiple thin washers. The damping piston slides in a restricting space located in the damping cylinder. The restricting space has an inside diameter smaller than the inside diameter of the damping cylinder. The additional counter-force is substantially constant throughout the entire stroke in order to create gentle braking of the damping movement.
