<p>The present invention relates to a damper capable of changing a damping force according to a rebound stroke, and more specifically, to a stroke sensitive shock absorber which enables selective control of a rebound damping force according to an operation stroke of a damper. The stroke sensitive shock absorber has a piston valve which is connected to a cylinder and a piston rod which divides the cylinder into a rebound chamber and a compression chamber. The stroke sensitive shock absorber includes: an inner flow passage which penetrates a lower end of the piston rod and makes the inside of the piston rod hollow with a certain depth; a connection flow passage connecting the inner flow and the rebound chamber; a free piston installed on the upper side of the piston valve and opening and closing the connection flow passage according to an elevation according to the piston rod; an elastic member elastically supporting the free piston upward; and a check valve installed on the lower side of the inner flow passage and blocking a fluid which flows from the lower side of the inner flow passage.</p> |
