Disclosed herein is an impact sensitive damper damping vibration transferred from a road surface to a vehicle, and more particularly, to an impact sensitive damper in which handling stability may be achieved in a low speed operating section of the damper and improvement of ride comfort may be achieved in a high speed operating section thereof. According to an exemplary embodiment of the present invention, there is provided an impact sensitive damper improving ride comfort by decreasing damping force when impact is applied to a vehicle, the impact sensitive damper including: a body valve body having compression channels and expansion channels formed therein; a fastener vertically penetrating through the body valve body; a dish shaped spring interposed between an upper portion of the body valve body and the fastener; and a disk shaped spring interposed between a lower portion of the body valve body and the fastener, wherein at the time of compression stroke when the impact is applied to the damper, the fastener is relatively displaced with respect to the body valve body due to elastic deformation of the dish shaped spring, such that the disk shaped spring and the lower portion of the body valve body are spaced apart from each other, thereby increasing a channel area of operating fluid. |
